From 87a9951cf8014c86a022bf05c9c025b65067811f Mon Sep 17 00:00:00 2001 From: Michael Sevakis Date: Tue, 8 May 2012 21:27:43 -0400 Subject: Consolidate some sample input code. Input functions have common setup sequences that can be placed into an inline function instead of repeating it all repeatedly.
