Persist TessBaseAPI over calls for better performance #4

Hi there! I see that, out of tens of tesseract_ocr forks, this one seems most maintained - thank you!

I don't know what are your plans, but core feature of my app is ocr, so I'm very interested in helping you to maintain this!

Okay, countresy aside - I see that the TessBaseAPI object is re-initiated every call:

Isn't this inafficient? Can we persist it somewhere and expose methods to init/dispose it?

Good idea. It's currently being developed for web support. I'll check it out when the web support development is done.

0.2 seconds faster per page than before I tested it with 10 pages. About 2 seconds faster.
