Title: Added qiime.filter.sample_ids_from_category_state_coverage function

Added ```qiime.filter.sample_ids_from_category_state_coverage``` function to facilitate filtering samples based on how well a subject/individual covers (i.e. has samples for) a given category's states.

A common use case is to perform filtering based on a time series study. You might want to filter out an individual's samples if they do not have samples for enough time points or do not have samples for "important" time points (e.g. the first and last time points in the study).

This resolves issue #453.
