    I enhanced VisIt to handle database readers that can provide 2D multi
    resolution versions of the data. When 2D multi resolution is enabled,
    the avtMultiresFilter adds a multi resolution data selection to the
    contract that contains the view frustum and a desired cell size. The
    reader then needs to return a data set that covers the frustum and has
    a cell size smaller than the desired cell size assuming that the mesh 
    covers the extents and has cells smaller than the desired size. The 
    reader also needs to add to the contract the actual frustum covered and 
    the actual cell size returned. A working example of a reader that 
    supports multi resolution data selection was added. It is the MRTest 
    reader and is built when specifying -DVISIT_BUILD_ALL_PLUGINS=1 with 
    cmake. I also updated the release notes with a description of the change.
