Baseline/Continuum Subtraction #181

Open keflavich opened 9 years ago

Baseline/continuum subtraction is commonly required for spectral cubes. We should incorporate more utilities for this purpose, e.g. generalized apply-a-function-along-an-axis methods (besides just numpy ufuncs).

For examples, see https://github.com/pyspeckit/pyspeckit/blob/master/pyspeckit/cubes/cubes.py#L106.
