introduce new method:

 getClusterSize(const IMPL::TrackerHitImpl * hit, int& sizeX, int& sizeY ) {
- intput IMPL::TrackerHitImpl object
- output: sizeX and sizeY in pixel pitch units / supposed to be integer
access cluster size information:

- for histogramming would like to cross study cluster size to residual
add LVL1 cuts on the minimum and maximum LVL1 selection

- should not be here, but in a Filter processor.
- this processor should go away anyway, so adding it in here now for not long
adding runlist for the list of runs with 1FEI4 in the mid of the telescope
