/**\class edmtest::MayConsumeWhatsIt
Description:
Consumes and produces EventSetup products.
This test module is similar to ConsumesWhatsIt,
but is focused on the "may consumes" variants
of the the consumes interface.
This is used to test the printout from the Tracer
module related to EventSetup module dependencies.
