Added new functionality to the RBF interpolator. First, users can now choose between using the slib implementation of RBF interpolation or a 'reference' implementation provided by rbf_interp_nd. This is controlled by setting the RBF function to use the 'Alt' signature. Second, for the slib implementation, the condition number of the matrix that is invereted in the RBF weight computation can be computed via a call to EnableConditionTest. The testing file has been updated to expose these changes.
All of the M's got deleted in the RBF interpolator. Put them back in
Changes to CMakeLists to disable ARPACK tests if it's not found.
Added in support for avoiding rescaling image to canonical sizes if parameters.imageCanonicalSize <=0
New files that support the new uses of the RBF interpolator
Added a new DetectionParameter called decafFeatureName which is a placeholder for an eventual sane implementation of all of this feature crap that is more abstracted and beautiful, but I gotta get shit done right now so it's going to have to stay in there for the time being
Updated STL sort routines to handle user-defined sorting functions correctly. Also added a decreasing-order comparator for ease of use
