Smearing parameterisations for the ePHENIX detector.

These parameterisations are non-exhaustive: they do not cover elements such as particle identification, and they are only for the central elements of the detector - essentially, just TPC and B/EEMC.

If multipleScattering == true, apply multiple scattering term to momentum resolution (currently only implemented for 2 < eta < 4). Otherwise just use the linear resolution term.

Note: you must gSystem->Load("libeicsmear") BEFORE loading this script, as ROOT needs to understand what a Smear::Detector is.
