/*
* This code builds a regular expression in order to more intelligently match
* camel-case and underscore names.
*
* For any but the first letter, the following replacements are made:
* A => [a-z0-9_]*A
* a => (?:[a-zA-Z0-9]*_)?a
*
* That means any sequence of lower-case or underscore characters can preceed an
* upper-case character. And any sequence of lower-case or upper case characters -
* followed by an underscore can preceed a lower-case character.
*
* Examples: (case sensitive mode)
* gAC matches getActionController
* gac matches get_action_controller
*
* It also implements the fully and first-letter-only case sensitivity.
