/*
 * Nice helper javascript to enable you to make some javascript commands any where
 * in your script and call them once the page has loaded. To use, simply call
 * onLoad.push() to add a function as an event:
 *
 * Pass in a function to be run
 * onLoad.push(my_onload_function);
 *
 * Note that onLoad.push() is called with the function itself, not the result of
 * calling the function!
 *
 * You also pass a string to be evaluated if your function requires parameters:
 * onLoad.push("function_call('one', 2)");
 *
 * but consider using an anonymous function instead, as this will give you more
 * immediate feedback on syntax errors:
 * onLoad.push(function() { function_call('one', 2); });
