Bugs fixed in new release

  • Fixed various typos and formatting issues in the documentation.
  • If the index of the pandas.Series passed into functions such as get_populations and get_observations was not contiguous, then the assignment step would not properly align the values returned by calling the function.

This is fixed by assigning the index of the returned series to that of the given series.
