'''
ldm.invoke.globals defines a small number of global variables that would
otherwise have to be passed through long and complex call chains.

It defines a Namespace object named "Globals" that contains
the attributes:

  - root           - the root directory under which "models" and "outputs" can be found
  - initfile       - path to the initialization file
  - try_patchmatch - option to globally disable loading of 'patchmatch' module
  - always_use_cpu - force use of CPU even if GPU is available
