ISO8601 time parser bug with different resolutions with range

[jbfaden]

In Autoplot, the bug is demoed with:

print DatumRangeUtil.parseISO8601Range('2016-05-20T07:46.19.400/07:46:19.8')

Sadie reported this.

This is handled when the differences is in the length of subseconds.

The following script should run without errors:

print DatumRangeUtil.parseISO8601Range('2016-05-20T07:46.19.400/07:46:19.8')
print datumRange('2016-05-20T07:46:19.400 to 07:46:19.8')
# print datumRange('2016-05-20T07:46.19.400 to 07:46:19.8')  # make sure error is clear about : vs .
print DatumRangeUtil.parseISO8601Range('2016-05-20T07:46/07:46:30')  # difference in minute/seconds resolution
print DatumRangeUtil.parseISO8601Range('2016-05-20T02/07')  # Hours has never worked, but this is a similar problem (tack on ":00" and then do as before)

#119 was a lost ticket. I've closed it and this one should be used.
