-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 row_cat and col_cat matrix functions
-make htmlify work right on tempalte function calls
-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
-make other widgets have a user settable style
-find all uses of std::rand() and replace them with rand_kernel_1
-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
