Terminal Command Line Evaluation

Added a command prompt to the Terminal so text can be evaluated using
javscript's eval() function. Static controller functions can be called
like "GraphController.toggleGraphing()".
Also added a previous command history so previous input can be cycled
through with up and down arrow keys.
GraphController refactor

Removed redundant statistics tracking in the Graph Controller and
refactored unique values into Stats.
Bugfix for Selection where the primary node could be null when it passed
out of scope from TimeSeries.
Graphing Camera and TimeSeries for Stats

Addressed compiler warnings from the Unity 4.2 update and split the
functionality of the camera between 4 files for each of the camera modes
(network, free, and now graphing) plus a controller.
Also added functionality to TimeSeries to invalidate Stats objects
DataFile refactor

Refactored loading of DataFile out to a new class to reduce some of the
complexity of DataFile
Also added invalidation of a file's stats when nodes or connections are
removed.
