Apply diffs to coards.py module to accept more ways to represent time

[GoogleCodeExporter]

This is needed for loading data sets from OceanSITES that are not 100% COARDS 
compliant but that may have Time Units that are CF compliant. The diff looks 
something like:

diff __init__.py.orig __init__.py
109a110,115
>     Parse a CF (ISO-8601) compliant data - ignore case::
>         >>> parse(0, "DAYS since 1950-01-01T00:00:00Z")
>         datetime.datetime(1950, 1, 1, 0, 0)
>         >>> parse(7, "days since 1950-01-01t00:00:00z")
>         datetime.datetime(1950, 1, 8, 0, 0)
