\brief Meta-function selecting the "calculation" type
\details Based on two input geometry types, and an input calculation type,
(which defaults to void in the calling function), this meta-function
selects the most appropriate:
- if calculation type is specified, that one is used,
- if it is void, the most precise of the two points is used
