- fits better into the general sampling framework, improves flexibilty
and allows code reduction.
ENH: include surface fields on sampledSurfaces that support it
- can be useful either for flow-rate weighting where backflow
is to be ignored in the average, or for flow-rate weighting
on surfaces with inconsistent orientation.
Reworked to code to make better use of Enum (the NamedEnum
replacement). Enum doesn't require contiguous enumeration values,
which lets us use bitmasking of similar operations to reduce
duplicate code.
- this makes it possible to perform additional operations
on surface values that have been previously sampled.
- support vectorField for weighting operations.
- reduce overhead by avoiding creation of weight fields, Sf fields
and combined surface geometries unless they are actually required.
- extend some similar concepts and operations to volFieldValue
