Adding multiple files with hadd

hadd usage:

Usage: hadd [-f] [-T] targetfile source1 [source2 source3 ...]
This program will add histograms from a list of root files and write them
to a target root file. The target file is newly created and must not 
exist, or if -f ("force") is given, must not be one of the source files.
Supply at least two source files for this to make sense... ;-)
If the first argument is -T, Trees are not merged
When -the -f option is specified, one can also specify the compression
level of the target file. By default the compression level is 1, but
if "-f0" is specified, the target file will not be compressed.
if "-f6" is specified, the compression level 6 will be used.
if Target and source files have different compression levels
 a slower method is used
