This is a very barebones prototype for a FrameWriter to write DataFrame objects produced by Onix1
Its core functionality is a set of Write methods for different types that can appear on DataFrames
and the use of reflection to dynamically inspect the source frame types, extract its properties and direct them
to the appropriate Writer method. Reflection mapping is done at startup so runtime invocation should be fast.
This could be a generic object writer. However, since we need to define specific writing methods for some specific classes, it would be difficult to maintain, while
