Matthias Boehm updated SYSTEMML-555:
------------------------------------
Description:
Full data frame support requires some modifications of existing builtin
functions, especially transform. This task covers these modifications as well
as related cleanups to allow seamless usage of transform in JMLC scoring.
1) Read parameter 'schema' (* for all strings, or list of value types; if
unspecified * for backwards compatibility).
2) Transform parameter 'spec' as string instead of 'transformSpec' as filename.
3) Transform recode maps inputs and outputs as frames.
4) Split transform and transformapply into separate functions due to different
number of outputs (alternatively: always return the recodemaps, even if already
passed in).
