--- a/docs/todo.txt
+++ b/docs/todo.txt
 move all the function bodies in widgets.h to cpp.
 Hide all windows header files in a cpp file.
 smart pointer that uses a memory manager.   think memory pool with pool pointers
 make a function to make a vector of vectors look like a matrix
 add something to unroll a matrix into a vector
 add row_cat and col_cat matrix functions
 add a quadratic classifier
 make a multiline text field
 make htmlify work right on tempalte function calls
 mutual information based feature selection
 make the popup menus from the menu_bar always put themselves on the screen
 add toggle menu item styles
 improve unicode support in on_keydown()
 make widgets take ustring as well as std::string
 add a popup menu region sort of like the tooltip widget
 make other widgets have a user settable style
 find all uses of std::rand() and replace them with rand_kernel_1
 add a function to display an image in a window.
 make the binary search tree's add function return a
 pointer to the thing it just added
 add an object that represents an atomic counter so I can make some thread
 safe reference counting stuff.  Probably use the one from boost.
 add an option to the logger to send log messages
 to a thread instead of writing them directly
 to the ostream.  Or maybe make a threaded streambuf
 that sits on top of a normal stream buffer but
 adds a thread for the io...
 make the matrix have a template argument that determined if the data is stored
 in row_major or column_major order.
 maybe add an enable_events() function to base_window
 add a toolbar_button that has a picture and text in it.
 make an ostream_fork object that lets you make an ostream that writes to two 
 other ostream objects.
 make something that parses strings of the form "key ='value'  key2='value'"
 add some sha-256 stuff
 uulib-threadsafe implementation
 http://www.fpx.de/fp/Software/UUDeview/
 add an example that uses the new checking extension for the cmd_line_parser.  maybe make a 
 program that adds numbers and whatnot as an example and have it validate the numbers or something.
 add some extensions to the dir_nav stuff that know how to pull out various parts of a path.
 like the parent directory of a file and such.
 make a widget that lets you use the mouse to define geometric shapes on the screen
 modify the if in the reference_counter::modify() function so that it works
 better with the branch predictor
 Add a progress bar and password field to the gui_widgets
 make sure constructors that take parameters that need to be checked
 get checked *before* they are passed on to the base class constructors.
 make the hashing objects take a normal size rather than expnum
 make a linear hashing object on top of the array and use a binary search tree
 for pathological buckets.
 *********************************************
 make conditioning_class_kernel_3 have a pointer into its array that tells it how many 
 elements are used.   this way it doesn't need to zero everything on construction.
 a command line "percent complete bar".   something that uses \r and looks like
 |==========                       | 25%
 or something like that.   that would be nice.   
 some object that abstracts configuration managment.  like windows has the registry and
 linux and posix stuff has basically nothing except for /etc and ~/.yourprogram sort of crap.
 I should make an object that lets you "save" information to disk and then get it later.  but
 you shouldn't need to know if you are using windows or a posix OS or any of that crap
 the parsing end event in the xml parser should tell you the line number that parsing eneded on
 an object which can fill an array of unsigned longs with primes
 look for places to remove the use of references to arguments. use a 
 temporary where appropriate
 make an implementation of sequence that is just an array with slack on each end
 something that mesures cpu clock ticks
 something that helps you make pdf files.  Just read the PDF standard and think
 up cool stuff. :)
 english word set with perfect hashing
 something that helps you find perfect hash functions for a given data set
 make something like the linker object but that has some events that tell you
 when data is being sent so you can see what each side is sending. 
 modify sequence_kernel_1 so that when you access the same element more than once at a time
 it takes O(1) time
 make some bayesian text categorizer
 implement the hash table described on comp.programming.  the one
 that uses an "infinite" array of buckets of sizes that are powers 
 of two with the watermark.
 also change the specs for hash table to say that the num_of_buckets is
 an initial suggestion as to the size of the hash table.  not an absolute 
 rule for the implementation.  say that it is a guaranteed lower bound or something
 an object that makes it easy to save data to the end of an executable file.
 email objects
 new sockets stuff, UDP sockets, non-blocking sockets, IO multiplexing, negal alg on/off
 make a priority queue
 an echo object for networking shit.   holds connections and echos any data from one connection
 to all the others
 a broadcast object.   holds connections and allows you to send data to all of them easily
 file sender function
 an object which represents a file containing many text lines
 like an array of strings which represents a file.
 make an object that facilitates the creation of a gnutelli like broadcast network.
 could be useful for making someting like a distributed server.  and that only requires a
 few computers so its something actually doable without the support of 100,000 people
 a few ideas about this.  when you connect to the first person on the network you then send
 out a ping message and the pong messages you get back are from people who want more
 connections,  the message tells you how many hops away they are and how many connections
 they currently have.  you pick the one that is the farthest away and then to break any
 ties you pick the one with the least number of connections.
 an object which allows you to replace strings in a file with something else.  possibly event driven.
 you give it a set of strings to look for and when it finds them you get an event and can write
 whatever you want and then it continues on looking for more strings.
 an object which will pick out all the links in an html file and any other convenient information from
 the file.
 make numerical stuff like, a big integer, big real, integration stuff, differentiation stuff,
 matrix stuff, etc...
 make a framework for creating web page interfaces to a program.  have stuff like buttons,
 listboxes, dropdown boxes, checkboxes, etc...
 a kind of pop3 proxy that can perform mail filtering.  like picking out and taging spam
 so that crappy email clients like netscape can put the spam into a folder
 the filter could also buffer stuff it thought as spam for a while.  like hold it for a few hours and then let it be passed on.  this way all the spam comes wrapped together.  and so most of the time you get a flag saying you have mail it won't be spam.  only somtimes will it be the packet of spam.   
 for the bigint object:
 also consider adding a function which returns an unsigned short which contains the two least significant bytes from the bigint
 an object which knows all about the different time zones and what not.  it could convert time from GMT to whatever local timezone you are in.  and any other useful conversions
