#854 new enhancement

WeylScal4 should have multi-process test cases

WeylScal4 currently has two tests, both of which run on a single process only. To test parallelisation, I propose that these be changed to run on two processes.

The tests can be made to run on two processors but then they generate different output from a single processor run. No combination of output_ghost_points and compact_format seems to give processor independent output. Essentially two processor output contains extra empty lines (and/or the component number in a column) whose presence is considered significant by the test suite scripts. The best one can do seems to be identical up to extra empty lines when adding

IOASCII::compact_format = "yes"
IOASCII::output_ghost_points = "no"
# we want symmetry and buffer points since their behaviour changed in the past
