Remove elasticity directory

Removing defunct sandbox directory from the elasticity branch.
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.
Merge remote-tracking branch 'origin/master' into issue69-nonperiodicBC
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.
Fix doctest verbose issue

Fix doctest by including directives to ignore the output from sfepy
generated while computing the strain field.
Add nosetests for resize_coeff method

Address issue #67

Add nosetests for resize_coeff to ensure that the method doesn't break
when added functionality to the package.
Add files to build docs.
Remove workshop names from notebooks

Address issue #52

Remove spaces and numbering in names of notebooks. Remove superfluous
notebooks.
Fix broken Makefile

Address issue #52

Makefile was not iterating over dependencies for each target. Now
using % to expand names in list of targets and dependencies.

 * Add Sphinx output directories to .gitignore.

 * Add all notebooks to docs.

 * Remove defunct elasticity notebook.
