closes #111
clean_state()
has an argumentmax_dist
. A higher value permits 'fuzzier' matches, a lower value requires stricter matches.This PR changes the default value of
max_dist
from 0.4 to 0.2. This will reduce spurious matches (as documented in the issue #111 ) at the potential cost of more failed 'true matches'. In my view this trade-off is worth it, and testing suggests this will not be a significant issue. Users remain able to manually specifymax_dist
if they do not want to accept the default value.
