Update Comment Format

Update most of the comments to functions and classes. Didn't change
any of the doctests.
Convert Comments to Google Python Style

The comments for each of the codes were converted from their original format to match the format provided by the Google Python Style Guide. http://google-styleguide.googlecode.com/svn/trunk/pyguide.html.
Move unimportant prerequisites inside functions and classes where used.

Move unimportant prerequisites such as Fipy, pyFFTW, etc. into the function and classes where they are used. User can import pymks without an error now.

Fix #56
Run autopep8 to clean up code

Run autopep8 to clean up code by removing unneeded white space. All the tests run will not errors.
Add learning curves and plot_learning_curve

Add the function plot_learning_curve to tools and add the learning curve plot to 'Cross Validation' notebook. This plot provides insight into whether the number of training samples is large enough.

Add learning curves and edit notebook `04 - Cross Validation`

Edit notebook `04 - Cross Validation`. Remove exercises from seminar
and provide examples for users to mimic. Add learning curves.

Fix test due to addition of coeff property

Address #49

Add fftshift to test coefficients as model.coeff now returns the
shifted real versions.

Merge branch 'elasticity'

Fix #49
Remove elasticity directory

Removing defunct sandbox directory from the elasticity branch.
Add numpy fftshift and numpy pad to resize_coeff

Address issue #67

Add fftshift and pad to the method resize_coeff to do the padding of
the influence coefficients in a more canonical way. The constant
valued influence coefficients still need to be addressed.
Fix constant valued coefficients and pad placement

Address issue #67

Fix constant valued coefficients to scale properly when zero padding
by increasing the size of all dimensions by an integer value. Still
need to look at scaling in 3D and for any shape.

The zero padded influence coefficients were not centered
correctly. Fix placement and doctest for resize_coeff.
Use __all__ in __init__.py

Address #52

Use __all__ in __init__.py for sake of API documentation. Also added
`-dev` to the version number.
Fix MKS elasticity test

Fix MKS elasticity by removing the boundary cell where the assumption
of periodic boundary conditions is not valid. The tolerance was also
increased slightly.
Fix Boundary Conditions and resize_coeff

Fix issue #67

Fix the boundary conditions for the ElasticFEModel to have the
macroscopic strain value for any size microstructure. The previous
boundary conditions were incorrect and were creating an error with
re-sized influence coefficients.

Fix zero padding of the constant coefficients. For the constant valued
influence coefficients, the k0 value stays the same regardless of the
re-sizing.
