In cannin/rcellminer: rcellminer: Molecular Profiles, Drug Response, and Chemical Structures for the NCI-60 Cell Lines

#' Returns a list of molecular data type matrices, with rownames in 
#' each matrix prefixed with a data type abbreviation.
#' 
#' @param molDataMats A named list of molecular data type matrices with feature data 
#' specified along the rows, and feature names indicated in the row names.
#' 
#' @return a list containing molecular data type matrices, with rownames 
#' in each matrix prefixed with a data type abbreviation, e.g., 'exp' for
#' mRNA expression, etc.  The matrix-specific data type abbreviations are
#' derived from the names of molDataMats.
