Added comments to MERTrackKalman3D.cxx to source equations used for energy estimation. Also put comments for future reference, as we had some questions about why some calculations are done in the code.
Commented out setting energy to Electron and Positron later in the code, as we used energy from the hits, not from multiple scattering. Added a for loop to include energies from all hits, not just those from the track, to match how the standard case sums energies of all hits.
