Whitespace removal; Added borders to the tables

Borders help you to see row/col spans
Lots of changes

* Tabs => spaces
* Remove some example tables
* Create a really degenerate table
* Change the API so the caller must pass a single selector for their
  tables
* User innerText instead of innerHTML
* Non printable ascii chars are wrapped in quotes
* Rewrite the CSV constructing code (sorry Issac) to handle degenerate
  tables
