Split the spreadsheet part of the readme into its own readme
Fixed a bad json parse bug

Json is being sent by the server, however when there is no data to send the server
sends a blank string. The javascript now catches the blank strings and ignores them
instead of trying to parse them into a json object

A logging command was also added to display the data being recived by the server
Fixed the bug where text in the cell selector was not selectable with the mouse
The Cell Selector box was beind a div that was catching mouse movements. The
solution was to put the cell selector inside of the div, allowing it to catch
its own mouse movements as well as apear behind the scroll bars when a cell
that is selected happens to exist behind the scroll bars

In the future this change may be reverted and the cell selector placed over the
scroll bars, as well as a feature that scrolls the spreadsheet over whenever a
cell off the screen is selected
