Added 'kde' 3rd-party lib.
Added cache-related functions.
Imported load/saveSorted functions from another repo.
Made hash key computation much (much!) faster for large cells/structs.

Trick is to convert to a ginormous string before calling md5 (that was the slow part)
Added simple caching function.
Fixed issue with cache function.
Slightly more verbose cache function.
Improved hash code with the help of CalcMD5.

Thanks to Jan Simon for providing this code!

Can have different bins for each dimension in multi-dimensional histogram
Renamed to pdist2_old

Use matlab's pdist2 now
Neat data tip 3rd-party code.
Added 'parallel' processing stuff.

Very simple. Uses the 'multicore' matlab package in the 3rd party libs.
