Documentation and more descriptive naming of functions & simplified interfaces, proper error reporting & catching needed

[Masterxilo]

CodeFormatterPrint should IMO be named something like PrettyPrintSymbolDefintions.

I don't think the names should include CodeFormatter as they are already in that package. Maybe have prefixes to avoid conflicts.

FullCodeFormat and consorts should IMO also accept non-box form expressions and do the conversion themselves.

Full documentation (with F1-ability) would also be nice once this matures some more.
