Version 0.2.1

Additions:

• gr.tran_pivot_wider() and gr.tran_pivot_longer() for reshaping data; patterned off of the pivoting tools in tidyr @OscarDeGar

Fixes:

• Docstrings for dfply functions (such as gr.tf_mutate) fixed; this makes it much easier to reference these tools when coding @OscarDeGar
• Eliminated some circular importing by restructuring core.py and tools.py; adding a new marginals.py to consolidate marginal-related tools @Riya-1
