Wraps a function to allow it to be called, at most, once for each sequence of calls fired repeatedly so long as they are fired less than a specified interval apart (in milliseconds). This can be used to reduce the number of invocations of an expensive function while ensuring it eventually runs.

Example use: For the callback to a change event on a ui.Checkbox. If the user clicks the checkbox repeatedly, only the last click of the checkbox will run the callback.

Returns the debounced function.
