Detailed Description

Tool capable of creating collections missing (early rejection) after HLT processing. It declares output handles for all possible collections produced by the trigger.

to add more classes follow these steps: 1) add EDM pkg in CMakeLists 2) add includes in this file 3) add DEF_*_KEY here 4) initialise it in initialize method (in cxx file) 5) add create in the createOutput 6) test

Fails when they are setup inconsistently: the only allowed setup is: views and in empty - then out can be of any length - this is mode to fill missing containers views and in not empty, have to be the same size - out has to be 1 - this mode is for merging from several views into one output if merging from several views into several separate output containers is required another instance of that tool can be setup
