/**
 * Class to work around the annoying queuing of multiple taps for Buttons. Could have a time attribute.
 *
 * This is useful as sometimes (on some platform / device combos) you can quickly tap on a button and end up
 * starting an activity more than one. The reuests seem to be queued before the action has taken place so
 * solutions like disabling the buttons or setting singleTop do not seem to work :(
 * 
 * Taken from: https://github.com/doridori/AndroidUtilDump/blob/master/android/AndroidUtilDump/src/couk/doridori/android/lib/view/SafeButton.java

Do you have an example of how to make an instance of this class?
