    Enhancements to SimV2: · 67cd6aab

    1. Domain nesting and domain boundary objects are now supported. SimV2 wraps
       the real avt C++ objects using a C API that hides all direct access to the
       objects. The static C lib dynamically gets the real implementations of the
       functions from the SimV2 runtime. This pattern will be implemented for the rest
       of the libsim structures to prevent errors in user initialization of simulation data
       structures.
    2. I created an AMR simulation of the Mandelbrot set to test the domain
       nesting features. See http://www.visitusers.org/index.php?title=Movies
    3. VisItDebug functions were added that enable the simulation to write
       printf-style output to VisIt's debug logs. I stole the pattern from Tom. Thanks Tom!
    4. The VisItUpdatePlots and VisItExecuteCommand functions were changed to be
       blocking using a new synchronization mechanism in SimV2. The functions
       block but still allow the simulation to process VisIt commands until the
       synchronization is complete. This gets the 2 functions working as one would
       expect and makes it much more feasible to write code where the sim saves
       images of its data as it progresses. The amr and updateplots simulation examples
       can actually do this now.
    5. The synchronization mechanism is exposed via the new VisItSynchronize function
        which blocks the sim until VisIt is ready to continue (if VisIt is connected).
    6. The command callback infrastructure was reworked to be a little simpler and
       allow for user-provided callback data. The gui was also fixed so it 
       sends the right commands in addition to the "enhanced" command names. A few
       issues were also fixed to make sure that the command callback infrastructure is
       compatible with the new synchronization mechanism.
    7. Block names were added to mesh metadata. The amr and csg example simulations use this.
