eval_ib_metrics_node_types()

First the distance argument determines the node types:

• distance > eps: the node is inner
• distance < eps: the node is outer Then outer nodes that neighbors an inner node is transformed into a ghost node.

The transformation to ghost nodes is active only is the argument add_ghost_nodes is set to true.

The transformation takes corners nodes into account only if add_corners is set to true.
