Detailed Description

Smears the four vectors of charged tracks according to dP/P = r for a given range of the polar angle.

The resolutions r are given in the constructor as a vector holding triplets of: r0, th_min0, th_max0, r1, th_min1, th_max1, ...
Perfect electron and muon ID is assumed to set the particle energy ( mass ) - all other particles are assumed to be pions.
