* ## Notes
*
* - The condition is evaluated *after* executing the provided function; thus, `fcn` *always* executes at least once.
* - When invoked, both the predicate function and the function to invoke are provided a single argument:
*
* - `i`: iteration number (starting from zero)
*
* @param fcn - function to invoke
* @param predicate - function which indicates whether to stop invoking a function
* @param thisArg - execution context for the invoked function
*
* @example
* function predicate( i ) {
* return ( i <= 5 );
* }
*
* function beep( i ) {
* console.log( 'beep: %d', i );
* }
*
* doUntil( beep, predicate );
