Added ability to specify colormaps via files and images
Removed kmeans files that are actually testing files, not part of the lib
Removed empty file curbf.cc
Small update to the job completion handler in Cesium. We now dequeue all indices a node was responsible for. We don't actually know whether those indices were completed (although that information is available via the output.indices variable), but the point is that we need to make these indices available for another node to process if they were not completed.
Added a small debug message in mpijob.cc to track the status of pending completion responses. Nothing major
Added support for nodes to explicitly indicate that they have died. This is useful, for instance, when a node is able to catch kill signals and then indicate it is about to die to the master
Added more functionality to the mpi_test_comm routine. The test now ensures that with a properly installed SIGSEGV handler Cesium can remove the node. This is not always possible nor is it always desired, but at least it is now possible
