// 20100507  M. Kelsey -- Use template arguments to dimension const-refs
//    to arrays,for use in passing to functions as dimensioned.
//    Add two additional optional(!) template args for piN/NN.
//    Add new data member "sum" to separate summed xsec values
//    from measured inclusive (tot) cross-sections.  Add two
//    ctors to pass inclusive xsec array as input (for piN/NN).
// 20100611  M. Kelsey -- Work around Intel ICC compiler warning about
//    index[] subscripts out of range.  Dimension to full [9].
// 20100803  M. Kelsey -- Add printing function for debugging, split
//    implementation code to .icc file.  Add name argument.
// 20110718  M. Kelsey -- Add inelastic cross-section sum to deal with
//    suppressing elastic scattering off free nucleons (hydrogen)
