1) I added mcurvit, which is another sample embedded viewer application that displays a multi curve plot of 2d rectilinear data. It also applies an index select operator to control the range of data from the mesh that is displayed. It can be run in a GUI mode or a batch CLI mode. The directory contains a README file that explains how to run it. 2) I corrected an error in a function that returns an environment variable as a std::string, where the routine would crash creating a string from a NULL point if the environment variable was undefined. git-svn-id: http://visit.ilight.com/svn/visit/trunk/src@7156 18c085ea-50e0-402c-830e-de6fd14e8384
