JS: Dump Helper (print_r)
/**
* Debug helper similar to PHP's print_r().
*
* This function was inspired by the print_r function of PHP.
* This will accept some data as the argument and return a
* text that will be a more readable version of the
* array/hash/object that is given.
*
* @param data
* array, object or hash (assoc array)
* @param level
* Optional
*
* @return string
* The textual representation of the array.
*
* @see https://gist.github.com/3547657
