adds an optional entry to registerDatablock that sets a flag in the datablock files to-be-executed DatablockFilesList ArrayObject that erases relative-path duplicates and surpresses overwrites. setting it again in a sucessively executed module will take ownership of the exclusivity. otherwise, all script files follwing the same general path will be executed.

adds an unRegisterDatablock to remove a given "relativePath / file" from the list
sets up an automatically-cleaned ExecFilesList  ArrayObject following a similar pattern, and executed for each callOnModules call, so that for instance all module::initServer(%this) entries are parsed, %this.queueExec feeds the vector, and opon completion of gathering the list, all are then executed in module-dependency order
