fix for issue 353 (num2date can no longer handle units like 'hours since 2000-01-01 0').
fix for issue 354 (num2date no longer supports multi-dimensional arrays).
fix for spurious UserWarning about endian-ness mismatch (issue 364).
make calendar name keyword for num2date/date2num case insensitive (issue 362).
make sure units parser returns time-zone naive datetime instance that includes UTC offset (issue 357). UTC offset was applied incorrectly in netcdftime.date2num and num2date.
use python datetime in num2date and date2num whenever possible. Remove duplicate num2date and date2num functions from netcdftime. Addresses issue #344. Add microsecond capability to netcdftime.datetime. Roundtrip accuracy of num2date/date2num now down to less than a millisecond.
use nc-config by default to find dependencies. setup.py modified to handle failure to find nc-config more gracefully (issue #340). If you wish to use env vars to point to the libs, you must first move the setup.cfg file out of the way (rename it to setup.cfg.save), or set USE_NCCONFIG to 0.
if endian-ness of variable is specified, adjust datatype to reflect this when opening a file (issue 346).
fix for issue #349 (seconds outside the range 0-59 in netcdftime.num2date).
