Removed setInputName in hOCR and cleaned docs.

I tested the hOCR method without calling `setInputName` and it
works fine without it, suggesting that this upstream Tesseract
issue requiring it to be set to the empty string has been resolved
in the version of Tesseract we are using (3.03-rc1):
https://code.google.com/p/tesseract-ocr/issues/detail?id=463

I also cleaned up the documentation a little bit since several
strings were longer than 80 characters and some docstrings were
not formatted correctly (like @param, etc.).
