Changes in Algorithm documentation
Some updates to Fluids
* the create method now takes an optional temperature and pressure, but defaults to STP
* added a test to the tests folder for just fluids
Moved run scripts to /test
* You may have to added some path directives for them to work
* See the other test scripts for this fix
Add interpolate_pore_condition and interpolate_throat_condition to Fluids
* Redirected fluid property methods to this function
Added Trapping mechanism to Ordinary Percolation
* Trapping can applied to the Pc_invaded list after the fact by calling OrdinaryPercolation.evaluate_trapping()
* Still not perfect.  Isolated trapped pores are not properly dealt with
Refined trapping mechanism
* This algorithm does a clustering of the defending phase to see which pores are DISconnected from the outlet, and labels these as trapped
* At the moment throats do not get trapped, only individual pores and clusters of pores are tracked
* An quirk of the algorithm occurs in 2D...because of boundary faces above and below the 2D plane a single pore is almost neven trapped, only clusters of 3 (1 internal and a top-bottom boundary pair).  These don't seem to show up on Paraview properly (when boundary pores are thresholded out).
Documentation updates
print statements to jth runscript
Merge branch 'develop' of https://github.com/PMEAL/OpenPNM into develop
Changes to Fluids to accomodate solid phase electron conduction
Added 'empirical' option to Fluids
- The idea is to allow user to specify polynomial coefficients for fits to data
- This would presumably be used for specific fluids
Added name as a top level attribute to fluids
Test script show how we might use the Python logger more effectively
Some changes in the transport code

Now, the solver is faster and more flexible. It can accept conductance
as a list or number. There are also some small changes in diffusivity
and run_script files.
Changed imports to be Python 3.3 compatible
Changed 2 lines that will break in Python 3.3
Fixed all print statements to be Python 3.3 compatible
Found and fixed 4 more lines that break in Python 3.3
Python3.3: Fixed __init__ files for each module to include the '.' before file names
Python 3.3: Fixed all lines in code that imported modules locally to include a '.'
