Module analysisTools imports local module dataTools incorrectly

[themowski]

We're having issues importing the pysheaf.analysisTools module because the module imports pysheaf.dataTools by simply saying import dataTools:

pysheaf/pysheaf/analysisTools.py

Line 25 in 23002b2

import dataTools

That works within the module since the file is local, but external programs that try to import pysheaf.analysisTools can't resolve this import of dataTools, since they don't know where the module lives.

The fix should be just replacing import dataTools with from . import dataTools in analysisTools.py.

We tested this fix locally and that resolved the issue -- import pysheaf.analysisTools worked as expected in our external program.
