v2.1.0

After setting up continuous integration through CIG, this version contains many technical improvements and compiler setting improvements that ensure the code builds on a variety of Linux and Mac OS X environments. Other changes are grouped by function below.

Simulation Checkpoint Saving is now supported. Specify a text file for output and the number of events to complete before saving the state of the simulation. The simulation can then be restarted from a specified checkpoint. New PyVQ functions were created to paste together multiple simulation files.

Fault Model Creation with the Mesher has been greatly improved. Stress drops are now computed by the mesher and saved to the fault model. Faults are better defined and used by the mesher to set stress drops. We have also implemented better tapering of the slip rates, ensuring constant stress drops along faults.

Many PyVQ plotting updates. We have many new features for analyzing fault models, improved empirical scaling relations for California earthquakes, and much improved subsetting options, automatic file-naming, and new features to make movies of the slip during ruptures.
