why copy-paste from LdaModel? Should it be moved to utils?

I'll move the common ldamodel and hdpmodel methods to the respective utils and matutils files after this PR is merged.

Need to make a few other changes to utils and matutils as well

@tmylk this keeps happening over and over -- watch out for this in reviews.

My bad, I had just copy-pasted this from the existing ldamodel code and missed this. Fixing it in a new PR where I make some changes to utils.
* Added print methods, lda_model * Added HDP tests * Changelog * Removed duplicate code * Removed duplicate code * Added import * Fixed Changelog
This is to address issues #901, and #952, and go towards fixing #945 - basically to attempt to clean up HDP as much as possible.
This includes only the HDP changes from the closed #996.
I'll make the other cosmetic changes, and moving the appropriate methods to
utilsandmatutilsin a different PR.
