From 2e9d47ac2c9a4ebf0821d10c766fafa85e6d3cb9 Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Tue, 16 May 2017 15:14:02 -0400 Subject: Rename formcalc files to better match contents MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Most files match the contents. The expression files are named to match their base type even though they contain all the expression subclasses.
