Sourpuss: Like feeding pickles to a cat(1)

Sourpuss displays the contents of one or more Python pickle files on standard output. Currently, this small utility targets pickled Pandas DataFrames and supports transforming them in simple ways. Other pickled objects (e.g. dicts, NumPy arrays, etc.) are coerced into DataFrames. By making it easy to answer simple questions via Unix pipelines, sourpuss lets you avoid constantly context switching between $SHELL and Jupyter/IPython.
