Filled in *naspects and *ntokens, *avg_ntokens_review, and *avg_naspects_review.
Reviewed the code for the lang stat and dist stat. Added the category stat back into the code.
Modified the plot method so that statistics of only one number won't be plotted (which results in error in output), and adjusted the labels so that the category plot labels are not overlapping.
Edits made:
*naspectsand*ntokens,*avg_ntokens_review, and*avg_naspects_review.
