SCMIRMusicPredictor

//As used in the algorithmic jury and early electronic dance music corpus analysis projects

//

//Trains up a three part model (timbre, rhythms, summed harmonic change) over a corpus. The model can then be tested on a target piece to see how well it predicts it. 

//

//Note that scores are relative to a given model. 

//REQUIREMENTS: you need to set some directories in the *initClass class method. 

//depends on KMeans from Quarks, and KMeansZArchive extension class for save and load
