New version of doc files
new input file with one sentence per block
Class to consolidate block processing functions
Updated block processing functions...

 - Added a function (getBlock) to InputProcessor that takes the 2D array and returns a list of blocks.

 - Added wordCount to BlockProcessor. It returns the total count of words in all blocks.
   (It is also counting the periods at the end of each sentence at this time.)

 - Test.py was also updated to demo these functions.
