adding two more scripts to do iterative alignment:

- alignm26.sh does Mimosa26 sensors alignment only, assumes plane IDs: 0,1,2,3,4,5
- align1fei4.sh does one plane alignment with ID= 20 (FEI4), the Mimosa26 planes are still: 0,1,2,3,4,5 (of course used as reference to build tracks)
fix internal flags, that the script actually is executed
uncomment removing of temp file1 and file2
remove exit 0 statement so that the script does more then one iteration
