Major switch from Value -> Node. The library compiles with the new API, but tests are still oldies, and don't compile

Updated the node/value classes with the new iterators, they compile until we try to instantiate anything

Made the 'data' member optional in node_ref - it's only created on-demand, so we don't waste extra memory every time we do Value tmp = v;

Switched memory to using shared nodes, and node_data to keep only naked node pointers, not shared nodes (to break the cycle, and we don't need weak pointers because their memory is guaranteed to exist, via 'memory')

Switched the 'pragma once' to only happen on MSVC, or gcc >= 3.4 (it was causing trouble on the sun compiler)

Marked Parser, Emitter, Node, Iterator, Mark, and Null for exporting to a DLL. It appears to work properly, although VS gives me lots of warning C4251 since I didn't export all data members of each of the above classes.

It seems that it's not necessary to export those members (as long as you can't access them), and most of them are STL instances, which apparently cause lots of problems for DLLs. (For example, you simply can't export instances of std::map; see http://support.microsoft.com/kb/168958.)
