// CHANGE HISTORY
// --------------
// ChangeHistory:
// 10 May 2007 creation by L. Desorgher
// October 2009 implementation of the mode where the total adjoint and forward cross sections are equivalent. L. Desorgher
// Documentation:
//
// Continuous processes act on adjoint particles to continuously correct their
// weight during the adjoint reverse tracking. This process is needed when
// the adjoint cross sections are not scaled such that the total adjoint cross
// section matches the total forward cross section. By default the mode where
// the total adjoint cross section is equal to the total forward cross section
// is used and therefore this along step weightcorrection factor is 1. However
// in some cases (some energy ranges) the total forward cross section or the
// total adjoint cross section can be zero. In this case the along step weight
// correction is needed and is given by exp(-(Sigma_tot_adj-Sigma_tot_fwd).dx)
