Release v0.7.0-alpha.5

API changes

• Changed base_price_ffill_shift to just ffill_shift
• Added quality adjustment to index_calculator
• Modified index_calculator so that it now accepts base_prices as a parameter, and fills and shifts them when it does.

Bugs

• Fixed in get_base_prices where .eq() method was being used instead of isin().

Release v0.7.0-alpha.4

• Fixed bug in get_base_prices
• Added function base_price_fill_shift

Release v0.7.0-alpha.3

• Changed get_base_prices so it now fills within year, and also shifts the values as default behaviour.
• The aggregate function now sets weights where indices are 'inf' to zero.
• The aggregate function ensures periods where all indices are invalid are set to NaN rather than zero to avoid
  a ZeroDivisionError and return NaN instead.

Release v0.7.0-alpha.2

• Fixed bug in subset_shared_axis: now using method .equals() instead of non-existent method .eq().

Release v0.7.0-alpha.1

• Added a subset step to aggregate and impute_base_prices to reduce DataFrame arg sizes when functions are applied using groupby.
