/**
 * 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.
