PRECEDING TOPIC:    `Join`
FOLLOWING TOPIC:    `Fracture`

After`JOINing`an object,`points`may overlap causing an excess of
unnecessary`points`.  Merge should be as a cleanup function after using
`Join`, or after importing objects from other programs (object modelers,
conversion programs, etc.) to remove any unnecessary`points`. Merge works
by combining points that exist in the same, exact position into a single
point.

NOTE: Extraneous points & faces can add to the size and/or complexity of
the object. This may significantly increase rendering (or screen updating
during editing) time.
