Part evaluation function in runSubdue.m has been put into a separate file called 'graphTools/getSubScore.m'. DL calculation now takes only non-overlapping instances into account, which results in a better evaluation based on MDL && Kolmogorov complexity when compared to the previous version. A parameter added in SetParametersCommon.m named 'overlap', determines whether overlapping instances should be taken into account in score calculation (evaluation) of a part. Duplicate nodes from vocabLevel are removed before costly inhibition step, thus resulting in a faster algorithm.
