From a database generated from the mta-turnstile-scraper, find the entries and exits for each row.
Converts columns ENTRIES to CUM_ENTRIES and EXITS to CUM_EXITS. Updates calculated entries and exits in ENTRIES and EXITS columns respectively.
Raw data only has cumulative numbers per row, so some math and massaging was needed to get the exact numbers at each logged time slot. Does it by finding all entries per unique turnstile and subtracting the CUM_ENTRIES from a previous entry. Also ignores negative entries/exits and entries with no previous CUM_ENTRIES/CUM_EXITS.
# first run
$ python mta_cleaner.py <path to db of data>
# then run to remove outliers only
$ python mta_cleaner.py <path to db of data> clean

This is pulled from Sept 2015 data only, so just a relatively small dataset.

42nd st wins by a huge margin if you group them all up. Not sure how different 42 ST- PA BUS is from 42 ST- TIMES SQ. Considering consolidating them.

The '7' exclusion is there to filter out the weird 42nd st stop that apparently has 'G' in it.
