Masking of Missing Modules in SCT_Digitization

Changed:
<
<
The proposed cosmic setup uses 504 barrel modules arranged in two phi segments. Up to and including version 00-00-19 of SCT_ConditionsAlgs the tool SCT_ModuleStatusAlg contained the offline locations of these modules hard coded. SCT_Digitization would then retrieve the SCT_ModuleStatusAlg tool and thus determine if a given hit (real or noise) took place in a module which was present in the arrangement.

The new version of SCT_ModuleStatusAlg, found in SCT_ConditionsAlgs-00-01-00 and later, fills a map of the modules which are present from a table of those modules listed by serial number and offline identifiers in the COOL conditions database. After the map is filled (through a callback) it can be interrogated for each hit which is processed in SCT_Digitization.

The new version of SCT_ModuleStatusAlg, found in SCT_ConditionsAlgs-00-01-01, fills a map of the barrel modules which are used from a COOL table. The table has 504 channels and as its payload holds the module serial numbers and their offline identifiers. After the map is filled (through a callback) it can be interrogated for each hit which is processed in SCT_Digitization.
