calcMI: Calculate Mutual information (MI)

Description

This function calculates Mutual information of actual and predicted individual identities in the dataset. It uses Linear discrimination analysis (MASS::lda) to predict individual identity. Settings for LDA are identical to those used in calcDS function, i.e., LDA uses leave-one-out cross-validation and priors are equal for each individual in dataset.
