Latest release (With-Cairo Branch) for Homebrew Mac OSX installs

With the exception of Anna's themes, this is the tentative finalized release we will be testing and optimizing for the application note. This release is created for access by our Homebrew installer on Mac OSX, which can be run by executing the following commands at your terminal:

$ brew install --build-from-source gtDMMB/core/RNAStructViz

For all other install procedures (i.e., besides brew on Mac OSX), see this user documentation for details of installing RNAStructViz from source.
