Close Spinner Dialog

A quick one....a community user wanted to close a Spinner dialog after a set period of time if the user had not made a selection. I had several goes at making this extension myself, but then @KUMARASWAMY came up with a solution and created the extension code. All credits for this, therefore, go to KUMARASWAMY.

All the extension does is just that, closes the Spinner dialog. Use a clock to set the time period.

Some BLOCKS to show how to use the extension:
