* description
*   - A plugin to sort child nodes by (sub) contents or attributes.
*
* Usage:
*   jQuery("ul#people>li").tsort();
*   jQuery("ul#people>li").tsort("span.surname");
*   jQuery("ul#people>li").tsort("span.surname",{order:"desc"});
*   jQuery("ul#people>li").tsort({place:"end"});
*
* Change default like so:
*   jQuery.tinysort.defaults.order = "desc";
*
* Changes in 1.0.2
*   - matching numerics did not work for trailing zero's, replaced with regexp (which should now work for + and - signs as well)
*
* Todos
*   - fix mixed literal/numeral values
*   - determine if I have to use setArray or pushStack
*
