  // NEUTRINO ENERGY RESOLUTION:
  //  Contains parameterizations of muon momentum and shower energy resolution.
  //  Overall energy resolution is then obtained by combining muon and shower
  //  resolutions in quadrature
  //
  // DOCUMENTATION:
  //  implementation for cedar: see doc-db #5807
  //
  // INPUTS:
  //  track momentum
  //  track momentum error ( sigma_{p} = p^2 sigma_{q/p} )
  //  shower energy
  //  shower energy error
  //  rangecurve (1=range, 0=curvature)
  //  containedvertex (1=contained vertex, 0=rock muon)
  //  detector (near/far)
  //  release (dogwood/cedar)
