Repeater

Class used via an implicit conversion to enable a times method to be invoked on Ints to repeat a given side-effecting operation multiple times.

When an instance of this class is constructed, 0 and any positive number may be passed as num, but a negative number will result in an IllegalArgumentException. If constructed with 0, the times method on the resulting instance will return without invoking the function passed to it. If constructed with 1, the times method will invoke the function passed to it once then return.
