Switched from c++11 NaN support to a more widely available NaN definition although not bulletproof
Implemented fast RBF interpolation via CUDA
Some minor optimizations to fastrbf. Sped things about 2x as far as I can tell
Added ostream operator for LatLon
Merge remote-tracking branch 'origin/master' into fast_rbf
Added projection routines to the image directory
Added CUDA finders
Added CUDA finders
Added option to turn fastrbf on/off
Added abort support to Cesium. The util/assert.h methods will now abort Cesium as well if it's been started
Added routine to get environment variables
Merge remote-tracking branch 'origin/master'
Merge branch 'master' into fast_rbf
Better handling of directory creation in Cesium routines
Added todo comment
Moved fastrbf constructors to top of file and added method to set parameters post-constructor
Switched casting operator for MatlabMatrix to be non-C style cast. It's now a function
Updated fast radial basis function method to use the inverse multiqudratic RBF rather than the multiquadric RBF
Fixed small 'error' so that fastrbf routine returns the best model it found during optimization rather than the most recent
Added consts as approriate in RBF methods
