_if(function expression, function onTrue, function onFalse)
Return a handler, that on invocation will forward all its arguments together with a 'next' handler to [expression]. [expression] should then invoke its 'next' handler with either true or false. Depending on the result, either [onTrue] or [onFalse] will be invoked.
max(val1, val2, val 3, ..., valN)
Return the greatest value that was provided. Supports unlimited number of arguments.
createInvokeBarrier(int num, function cb)
Return a function that will wait [num] times before any call [cb] will be forwarded.

Return a function that will wait [ms] ms before cb in be automatically invoked with a timeout error if the function has not been invoked before that. The function will quarantee that [cb] is only invoked once.
