commit 4968170637ebc61fc0055fd3d9296411bd4e958f
Author: Brad Aagaard <baagaard at usgs.gov>
Date:   Thu Jan 23 17:17:22 2014 -0800

    Switch a bunch of newSection() calls in reassemble unit tests to new approach.
    
    New approach is compatible with multiple fields and higher order cells. Still need to plug memory leak.
