/* idTabs ~ Sean Catchpole - Version 1.0 */ 
 
/* Options (in any order): 
 
 start (number|string) 
    Index number of default tab. ex: idTabs(0) 
    String of id of default tab. ex: idTabs("#tab1") 
    default: class "selected" or index 0 
 
 return (boolean) 
    True - Url will change. ex: idTabs(true) 
    False - Url will not change. ex: idTabs(false) 
    default: false 
 
 click (function) 
    Function will be called when a tab is clicked. ex: idTabs(foo) 
    If the function returns true, idTabs will show/hide content (as usual). 
    If the function returns false, idTabs will not take any action. 
    The function is passed three variables: 
      The id of the element to be shown 
      an array of all id's that can be shown 
      and the element containing the tabs
