/**
  <p>A way to find a classname by supplying a prefix piece of a classname.
  This is used as a simple way to both have a selector and a meta string to the selector</p>

  @author <a href="dilltree.com">Jeremy Dill</a>
  @param {Object} obj The html dom object or jquery object that has class applied
  @param {String} cl The class begins with this.. example to find "lnk_test", set this param to "lnk_"
  @param {Bool} rip If true, remove the cl piece of the classname and return the remainder
