-Reserved Names
-##############
-
-In order to help out, CodeIgniter uses a series of function, method,
-class and variable names in its operation. Because of this, some names
-cannot be used by a developer. Following is a list of reserved names
-that cannot be used.
-
-Controller names
-----------------
-
-Since your controller classes will extend the main application
-controller you must be careful not to name your methods identically to
-the ones used by that class, otherwise your local methods will
-override them. The following is a list of reserved names. Do not name
-your controller any of these:
