Export _momentum_type #31

Open szabo137 opened 5 days ago

szabo137 commented 5 days ago

The function _momentum_type is sometimes used to get the scalar element type, e.g. to produce the correctly typed nil using zero. Therefore, it would be good to make it publicly available.

One could also make momentum_type an interface function for AbstractPhaseSpacePoints.

Alternatively, one could require the implementation of Base.eltype for subtypes of AbstractPhaseSpacePoints, i.e. making this part of the interface.
