Hadron level Monte Carlo generator for ep and pp scattering

The Monte Carlo program CASCADE generates a full hadron event record
according to the HEP common standards.
CASCADE was originally intended for small x processes and
used only gluon chains in the initial state cascade.
With the development of the Parton Branching TMDs, which are valid over
a large range in x and Q2, new developments were possible in CASCADE3:
CASCADE3 (apart from the older features) makes use of LHE files (either from collinear NLO calculations like
MC@NLO or off-shell calculations from KaTie/Pegasus) and has a full flavor
initial state parton shower, which follows directly the TMD from the Parton
Different sets of TMDs are now accessed via TMDlib.
