From 8e5038f8a27b6275633e1015e7d0a480a6e8ae51 Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Thu, 30 Mar 2017 10:43:35 -0400 Subject: Rename fgas_stream to ifgas_stream MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This Cl renames the the fgas_stream files to match the internal ifgas_stream class. The majority of the code in ifgas_stream.cpp is moved into the anonymouse namespace.
