Function returns ndarray of gene expression values from ndarray of unmodified data set and ndarray of gene indices
:param unparsedArr: numpy ndarray of unmodified data set
:param nnGeneIndex: numpy ndarray of indices of genes of interest
:return nnGeneExp:  numpy ndarray of data set including all cells and expression data only of genes of interest
