Additional parsing methods

[Steveorevo]

For decades I've created and used these very methods in Java, Perl, asp, php, xojo/realstudio, vb, lingo, and of coarse javascript & actionscript,. stringjs is by far the most orderly and comprehensive and I've decided to simply adopt it in lieu tacking on additional methods to my own. I've found parsing various proprietary files and data streams easier by chaining methods like delLeftMost, delRightMost, getLeftMost, getRightMost methods (particularly when purposely scanning from right to left or left to right). While probably not as efficient as regular expressions in some cases; it has made arduous complex parses concise and simple. Please consider adding these to stringjs core.
