Request adding source page number and returning with search result

[Matt-Scheetz]

At times there are documents we are uploading that contain dozens or hundreds of pages. It would be nice to include the page number or approximate page number, maybe a range, of where the cited data was found.

Update: I started looking into it and made a few changes in #201 - This will need some more involved work, revisiting how text is extracted. It's doable, but not straightforward, because the current text extractor goes from 1 binary file to 1 text file, without carrying over any metadata. Stay tuned :-)
