def GeneralSetup.setup	(		process,
			global_tag,
			zero_tesla = False,
			geometry = ""
	)

General setup of an alignment process.

Arguments:
- `process`: cms.Process object
- `global_tag`: global tag to be used
- `zero_tesla`: if 'True' the B-field map for 0T is enforced
- `geometry`: geometry to be used (default is an empty string for the standard geometry)
