Wrap R Functions for Debugging and Ease of Use

Provides 'DebugFnW()' to capture function context on error for debugging, and 'let()' which converts non-standard evaluation interfaces to standard evaluation interfaces. 'DebugFnW()' captures the calling function and arguments prior to the call causing the exception, while the classic 'options(error=dump.frames)' form captures at the moment of the exception itself (thus function arguments may not be at their starting values). 'let()' rebinds (possibly unbound) names to names.
