Initial setup
Added function to compute SSIfisher.
Changed property 'circular' from a bool to contain modulo value when stimulus is periodic.  Value is zero when non-periodic therefore boolean tests still hopefully work.
General tidying up, removal of old commented code.
Gathered mSSI prep calcs into one if statement.
Fixed MI function sampling code.
Changed some function names to sidestep really stupid MATLAB license issue.
Made a number of minor code changes recommended by m-lint.
Commented out some unused code.
Tideied up and updated some comments.
Added radians/degrees conversion functions to overcome more pointless licence/dependency issues.
Added CircGaussNeurons class.
Proper implementation of radToDeg.
Test of cleanup using stage on deleted files.
Cleanup of deleted files.
Removed some temporary/system files from cache.
Added ability to calculate SSI for selcted stimulus ordinates only.

Also fixed bug in mSSI calculation relating to how pS was repmat'ed in the calculation of p(r,s).
Added mex file for cellsxfun().
Added modified SSI function Neurons.ssi2, which used bsxfun and cellsxfun to eliminate the use of repmat and reduce memory usage.
Stripped out some asserts, updated help message.
Added code to detect problems with additive consts, also changed way const is applied in mi().
Checked in smoothness measures in new location.
Updated Neurons.mi() to use log probabilities for the sake of numerical stability.
Some moved and removed files.
