DockIntoDensityMover refactor 02 (#5497)
In anticipation of releasing some other code that uses this machinery I'm refactoring some parts of the DockIntoDensityMover to be functions rather than a class member functions so that other classes can use them. This is strictly a refactor and shouldn't change anything except the accessibility of some functions.
This refactor specifically moves to another file as functions:
get_radius
get_spectrum
apply_transform
select_points -> select_density_points
RBfitResult
RefinementResult
RBfitResultComparitor
RefinementResultComparitor
PointScoreComparator
ResultDB
RBfitResultDB
RefinementResultDB
DensitySymmInfo::mask_asu -> becomes a const function
