ndi.globals.assert

  ndi.globals.assert - check that ndi_globals has been initialized properly

  [B,MSG] = ndi.globals.assert(ndi_global_variables, ...)

  Returns true if the variable ndi_global_variables has been initialized properly. 
  Returns 0 otherwise, and, by default, triggers an error.
  Also returns the error message in MSG, if applicable. If there was no error,
  MSG is empty.
