Added Sentence Segmenter in Python Scripts

A "Sentence Segmenter" is an application created in python with tkinter gui.
In this application, user will be able segment any paragraph or text.
We need this application because paragraph and huge text are sometimes very tough to read and understand.
So using Sentence Segmentation, we split a given paragraph of text into sentences, by identifying the sentence boundaries.
for implementing this regex, that automatically detect which should be the correct sentence boundary and splits the sentence from there.
