//! \brief Selection list supporting soft selection and symmetry. 
/*!
This class implements a selection list that support soft selection and symmetry.

The rich selection is split into two halves: the "normal" side, and an optional
symmetric component. Components on both sides can include weight data which is
used to specify both the amount of influence and the proximity to the centre of
symmetry. 

In addition to the selected objects, the rich selection also includes information
about the axis of symmetry so that operations can determine how to process any
symmetric selection (e.g. reflect transformations, etc).
