serialization layer + housekeeping

[serialization][3hrs] Finished support for Dictionaries. Integrated a nuget package that does deep (reflection based) comparison of arbitrary objects to see if they are value-equal. Used that to add some tests of some very hairy compound containers. 

[environment][2.5hrs] Started putting together project directory. Ported over serialization from its test project. serialization will be the first feature, and a testground for exercising some of the facilities of the project: unit testing, code validation, and the core mosstool for doing things like updating the TypeMap.
