Remove classes that have given prefix

jquery_removeClassByPrefix

/*
 * Remove classes that have given prefix
 * Example: 
 *   You have an element with classes "apple juiceSmall juiceBig banana"
 * You run:
 * $elem.removeClassByPrefix('juice');
 * The resulting classes are "apple banana"
 * NOTE: discussion of implementation techniques for this, including why simple RegExp with word boundaries isn't correct:
