More detailed parameterised scattering for no UT scenario
Introduce reference EndUT
node in PrKalmanFilter
. This way the scattering transition is split into two in the case of no UT scenario.
(also renames TT->UT in few places)
Aims to address #379 (closed) and observed mass peak shifts.
Needs LHCb!3969 (merged) Allen!1160 (merged)
Closes #379 (closed)
