Add support for matrix transpose.  Note that the runtime currently only
  supports transpose for 2x2, 3x3, and 4x4 matrices.

  More optimization of the case when we do not need BSP semantics (plus some
  cleanup)

  Fix for linking on Linux

  Fleshing out various features, such as ":" and 3rd-order tensor support

  Working on ":" support

  Add support for 3rd-order tensor norm and fix issues with tensor/vector multiply

  Added length function on dynamic sequences

  Changed "ln" function to "log"; added "acos", "asin", and "atan" functions; restructured
  the way that C math functions are handled in the compiler.

  Add support for snapshots

  Some cleanup in the freeing code

Fixed memory leaks.

  Switch to using a biffMsg struct to record errors in the world.

  Fix copy code for reals and vectors

  Bug fix for copyToC.

  cleanup some FIXMEs

  Add global input registration support for standalone executable

  Add support for setting the number of workers for the parallel target

  Cleaning up the header files; support C++ as application language.

  Clean up the handling of translation from TreeIL types to C types.  There are two cases:
  translating to the external C API amd translating to the internal Diderot types.

  Update comment

  factor out input/output names into RuntimeNames module and change
  naming scheme

  Change convention for naming inputs and outputs

  Fixe some type errors in generated code.

  Added support for setting image inputs from nrrd objects; better propogation of
  errors; better use of world err field for error messages.

  Add support for building 3rd order tensors

  Rewrite of nrrd code to handle a single data axis for tensor data (and no axis for
  scalar data)
