  PMF refactoring

Remove approximate option. All processing will use what we formerly referred to
as "approximate". All code related to non-approximate is removed.

Add exponential option. The default behavior will continue to be to grow window
sizes exponentially (no change to users), but we now offer the option of
growing window sizes linearly.

Remove slow running PMF tests. Approximate is actually significantly slower
than the non-approximate variant for these test cases because the data is so
sparse, but the cell size is still quite small.
