Added support for Throotler

[malcommac]

Throttling wraps a block of code with throttling logic, guaranteeing that an action will never be called more than once each specified interval. Only the last dispatched code-block will be executed when delay has passed.

Example:

let throttler = Throttler(time: .milliseconds(500), {
  // your code here
})

// Call throttler. Defined block will never be called more than once each specified interval.
throttler.call()
