Added the IndexText Function

Now, CCFS can index the blob texts and display its contents in the index page.
Created the variable textIndex which is a map from Tokens in blob to the HCIDs containing the tokens.
Implemented the Full Text Search on the search page

Created a Text template to properly display the search results when the query is seeded with a text in a blob
