Improvements to to_tensorflow and BBox, Classlabel schemas

[AbhinavTuli]

to_tensorflow now works better with Text data.
ClassLabel and BBox schemas now support multiple ClassLabels and BBoxes. Better shape checks also added for both of these. Docstrings also improved. This should replace most usecases for Sequences
