Using the formalism explained in these lecture notes, the phasespace volume can now be computed using only masses in the initial state and in the final states as input. You can choose between two types of algorithms:
phspVolumeMC: Monte Carlo integration (aka hit & miss)
phspVolumeRiemann: Riemann integration
Benchmarks in PhspVolumeTest show that Riemann integration is faster than MC integration up to 5 particles in the final state.
