illustrate the use of e^+ e^- algorithms

They mostly differ from the pp algorithm by the fact that rather than using a radius parameter and inclusive jets, they use exclusive jets in one of the following ways:

a fixed number of them
with a dcut
with a ycut

Note that natively, FastJet includes the kt (ee_kt_algorithm) and genkt (ee_genkt_algorithm) algorithms. Others (like Cambridge for e+ e-, Jade or SISCone in spherical coordinates) are available as plugins (see 03-plugin.cc)
