caculate time_ranges

[wutongluxjtu]

Hi, professor Dan
Shouldn't the _caculate_time_ranges() function modified as:

def _calculate_time_ranges(self, hits, id, mode, mintime):
"""Given the id and mode, return the actual time support."""
match_times = sorted(hits[row, 3]
for row in np.nonzero(hits[:, 0]==id)[0]
if mode + mintime - self.window <= hits[row, 1]
and hits[row, 1] <= mode + mintime + self.window)

and execute: min_time, max_time = self._calculate_time_ranges(hits, id, mode, mintime) in _approx_match_counts().

since (mode+mintime) physically indicates real time_skew.
