Delete method signature

Deletes any additional information / documentation of a Express-x mapping method from the EDMdatabase.
Query functions already have their parameters defined in the query function signature. Hence, they implicitely get a method signature definition in the ExpressDataManager model and they may therefore not be deleted. Therefore this method is only applicable on Express-X mapping schemas.
Arguments:

Method type:	Specify type of method. XPX for mapping methods is the only method signature type that is legal to delete.
Method schema:	Specify the name of the Express-X mapping schema.
Method name:	Specify name of method

Options:

accumulating command output:	A global option that appends the command output to the EDMsupervisor output window. Otherwise the output window is refreshed and only the last command output is displayed.
match selected input:	A global option that specifies that only items that partly or exactly matches the string in the related argument input field when activating a Select button, will be in the selection list. An empty (blank) string will match all items.
