phpnut 6baaa1120f [1125] 
Adding empty directories where overrides for the core views can be placed.
Adding an empty directory for elements 

[1127]
Adding directory to hold core inflection files 

[1128]
More work on the new inflector.
This still is not completed but should be soon

[1130]
Documentation strings, du jour.

[1131]
Docstringed and ready. Inflector lacks one docstring. It is noted in its todo

[1132]
Incomplete documentation, and some corrections to previous documentation.
Gwoo noted that there'll be more changes in the Helpers soon, so I back off here.

[1134]
Adding before filters back to code.
Commented out a regex in Inflector::pluralize(); that os causing problems.
Removed a duplicate define in index.php.
Removed the bare array being set automatically when using requestAction().
With this change you must use requestAction(); like this.
$object->requestAction('/bare/controller/action/param');
Added GOTCHAS file with links to problems people may have with CakePHP.
Some more work done on new Inflector. 

[1135]
Added a check when trying to access a private method of a controller.
This will now display an error page informing user that this is not allowed. 

[1137]
Fixed a few undefined variable errors in the code
Corrected problem with double layout display when an error is returned and caught.
