Detailed Description

The gTower class is an interface object for gFEX trigger algorithms The purposes are twofold:

to provide inputs to the algorithms in a way that reflects the cell structure within a tower (the basic element of an gFEX algorithm window)
to hide the details of the individual data sources, e.g. which hadronic cells are LAr and which are HEC, from the algorithms It needs to contain supercell ET values and a tower coordinate or identifier (not yet defined). ET values should be on the gFEX's internal ET scale, not MeV. This should be a purely transient object, but will need to enter the transient event store (so class_def etc will be needed before it can be used for real)
