Foam::label countPointUsage	(	const scalar	minCos,
		boolList &	pointCanBeDeleted
	)		const

Mark in pointCanBeDeleted the points that can be deleted.

(parallel synchronised) and returns the global number of these points. (this number is the global number before synchronisation so might be off!) A point can be deleted if

it is not used by any edge. or
is not used by an internal edge
is used by only two boundary edges. (note that these two edges will always be boundary ones!)
these two edges are sufficiently in line (cos > minCos)
all processors agree that point can be deleted.

void setRefinement	(	const boolList &	pointCanBeDeleted,
		polyTopoChange &	meshMod
	)

Play commands into polyTopoChange to remove points. Gets.

boolList (output of countPointUsage) as input. Does no check for whether resulting face is legal. Since pointCanBeDeleted is synced all coupled faces should decide the same.
