Function Documentation

def Config.checkImportPermission	(		minLevel = 2,
			allowedPatterns = []
	)

Raise an exception if called by special config files. This checks
the call or import stack for the importing file. An exception is raised if
the importing module is not in allowedPatterns and if it is called too deeply:
minLevel = 2: inclusion by top lvel cfg only
minLevel = 1: No inclusion allowed
allowedPatterns = ['Module1','Module2/SubModule1'] allows import
by any module in Module1 or Submodule1
