move resamplers out of parsers?

[sbillinge]

Problem

Why are resamplers in the parsers sub-module, they are not parsers?

Proposed solution

create a tools sub-package, or simply put the resamplers into tools.py? Let's discuss what makes the most sense. @Sparks29032 ?

@sbillinge @Sparks29032
tools.py seems to only deal with user and package related functions. The documentation also has resampler in its own section, so should we just create a resampler sub-package? It would be diffpy.utils.resampler.wsinterp

Or instead we could do diffpy.utils.tools.interpolation.wsinterp

[Sparks29032]

I made a note in #145. I agree the import from diffpy.utils.resample import wsinterp (path diffpy.utils.resample.wsinterp) would be best. Right now the path is from diffpy.utils.parsers.resample import wsinterp.

This means we should pull the reample function out of parsers. However, we should check our codebase to see where resample is used.

@Sparks29032 from diffpy.utils.resample import wsinterp yeah, sounds good! @alisnwu let's proceed with this: utils/resample.py.
