Finished the bulk of the Sphinx documentation
The wait directive is processing properly again
Wait wasn't working + sendkeys uses lightconfirm

Wait was using lightconfirm which didn't notice an overflay
disappearing, as it was still in the DOM.
Sendkeys uses lightconfirm now to save cycles.
Block of code in waitToDisappear had a typo

Previous fix allowed the code to be called now. It appears that kwargs
were being improperly recursivelly passed and driver.logMsg was called
instead of driver.child.logMsg.
Stray characters at the bottom of a file
Added an element cache feature, modest speedups

Basically WebDriver was searching for an element every time, even on the
same page. I have now changed it so that it caches elements with the
same identifier / page and clears them out on a new run.
Workaround for common exception
Added missing cache file (and added doc to it).

Also changed exists timeout on waitToDisappear.
