[Suman Saurabh <ss...@gmail.com>]

Hi all,

This is regarding to Stanbol-1007 [1] issue. Sppech To text Engine has been
built [2].
1) Provides default model files for SpeechToText Enhancement Engine.
2) Loads Model file using DataFileProvider Service
3) SpeechToText Enhancement Engine
     - If no model files are parsed, uses default model files to enhance
the extracted text.
     - Added the support for parsing custom model files and the bundle name
from which model files are to be parsed.
     - Enhancement Results shows of the temporal position of the extracted
text

README has been added to get further insight. Enhancer Engine has been
tested with Stanbol .

Suggestions and comments are welcome.

Regards,
Suman Saurabh
