> Currently FrameObject uses the default toString() implementation. It would be good to override toString() in FrameObject, similar to how MatrixObject overrides toString().
> For example, using the MLContext API, if we currently output a MatrixObject and a FrameObject, it looks similar to the following:
> {code}
> scala> val res = ml.execute(dmlScript)
> res: org.apache.sysml.api.mlcontext.MLResults = 
>   [1] (Matrix) tA: Matrix: scratch_space//_p7667_9.31.117.12//_t0/tA_290, [3 x 2, nnz=6, blocks (1000 x 1000)], binaryblock, dirty
>   [2] (Frame) tAM: org.apache.sysml.runtime.controlprogram.caching.FrameObject@6c6c4579
> {code}
> The MatrixObject provides useful information via toString whereas FrameObject doesn't.
