"""
Calculate the difference of two datasets (ds - ds2). This is done by
matching variable names in the two datasets against each other and taking
the difference of matching variables.
If lat/lon/time extents differ between the datasets, the default behavior
is to take the intersection of the datasets and run subtraction on that.
However, broadcasting is possible. E.g. ds(lat/lon/time) - ds(lat/lon) is
valid. In this case the subtrahend will be stretched to the size of
ds(lat/lon/time) so that it can be subtracted. This also works if the
subtrahend is a single time slice of arbitrary temporal position. In this
case, the time dimension will be squeezed out leaving a lat/lon dataset.
:param ds: The minuend dataset
:param ds2: The subtrahend dataset
:param monitor: a progress monitor.
:return: The difference dataset
