the FastJet namespace
Order(N^2) clustering.
all the fastjet-related material is put under that namespace
Works for any class BJ that satisfies certain minimal requirements (which are ...?)
just provide a typedef for backwards compatibility with programs based on versions 2.0 and 2.1 of fastjet.
Since there is no easy way of telling people this is deprecated at compile or run time, we should be careful before removing this in the future.

given a vector of values with a one-to-one correspondence with the vector of objects, sort objects into an order such that the associated values would be in increasing order (but don't actually touch the values vector in the process).
bool fastjet::floor_ln2_less | ( | unsigned | x, |

returns true if floor(ln_base2(x)) < floor(ln_base2(y)), using Chan's neat trick...

const double fastjet::MaxRap = 1e5 |
Used to protect against parton-level events where pt can be zero for some partons, giving rapidity=infinity.
KtJet fails in those cases.
