attempt at switch for calculating population frequencies

[savitakartik]

switch works, but there's an issue. I have to delete the cache directory everytime I change the switch between True and False as it will otherwise use the cached df.

any suggestions how to avoid this issue?

calc_population_frequencies needs to be an argument of the cached function, rather than accessed from self. Arguments are included in the cache key.
