Creates power analysis code
Fixes spelling issue
Fixes formatting issues

Fixes pep8 and flake8 format issues
Also comments out alignment in the __init__ file since this was causing
the data to error.
Fixes import random error
Fixes more imports because pep8
Fixed spacing issues
removes unnecessary imports
Adds alignment back in to __init__
Switches from python to numpy

Substitutes numpy.random.choice from python’s random.sample. This will
coerce data to be numpy vectors.

It should also hopefully fix the Python 3 compatibility issues.

Also moves the test functions to a more appropriate folder.
Increases tolerance on confidence bound
Handles numpy compliace and testing

Continues the switch from python to numpy, including setting a random
numpy seed which should hopefully work with python 2 and python 3.
Moves the random seed into setup

This should hopefully fix randomization issues between the Nose module
and the Python test module.
Adds a function for subsampling

Introduces subsampling to get even sized groups for comparison with a
p-value similar to the p-value of all the data.
Adds alignment to _init__
