AE: Adding the latest ROOT source tarball
AE: Adding a script to install ROOT from source
AE: Actually add the install prefix as the install directory
AE: Turns out /gpfs/home/edmonds_a/AlcapDAQ/root-install isn't defined yet, so add a proper directory path
AE: For some reason this command doesn't work when running this script so you will have to do it yourself.
AE: Adding the call to thisroot.sh into thisdaq.sh
AE: Modifying .gitignore so that all the ROOT directories are ignored
Merge branch 'feature/AE_adding_ROOT' into develop. AE: We now have a single ROOT tarball and a script to install ROOT. This means we will all have the same version of ROOT and also avoids the plugin manager problems we were having on Merlin.
