/*@

DMPlexFindVertices - Try to find DAG points based on their coordinates.

Not Collective (provided DMGetCoordinatesLocalSetUp() has been called already)

Input Parameters:

+ dm - The DMPlex object

. npoints - The number of sought points

. coords - The array of coordinates of the sought points

- eps - The tolerance or PETSC_DEFAULT

Output Parameters:

. dagPoints - The array of found DAG points, or -1 if not found

Level: intermediate

Notes:

The length of the array coords must be npoints * dim where dim is the spatial dimension returned by DMGetDimension().

The output array dagPoints is NOT newly allocated; the user must pass an array of length npoints.

Each rank does the search independently; a nonnegative value is returned only if this rank's local DMPlex portion contains the point.

The tolerance is interpreted as the maximum Euclidean (L2) distance of the sought point from the specified coordinates.
