added numdiff binaries to repo
so tests can be ran more independently

also added mad-x for Linux
no need for Windows at the moment,
since the mad-x scripts anyway creates
soft links to afs which is not possible
on Windows.

the right binary is detected by ctest
remove madx binary
output reference files for new test added
tests in tests/ folder using only ctest
the bash script have been removed so they can in principle run
on all platforms
but mad-x script is still afs dependent though..
three columns in
chromcoupling.out were repeated..
upating ref files for tests
added executable mode to the valid Drive
ctests can now be ran directly from source directory
just start the executable.
can also list all tests with
ctest -N
and run a set of tests only using regular expressions, e.g.
ctest -R b1_acdata
numdiff tests should depend
on getsuper test
Merge remote-tracking branch 'github/master'
added ctest setup file
makes things cleaner..
added drive test
fix when valid folder is not created
