PlainBoundaryElements

definition of a plain geometry directly in MESHFREE

Some boundary entities can be defined manually via
begin_boundary_elements{} ... BND_entity &AliasName& coordinates GeometryManipulations ... end_boundary_elements
Alternatively, the alias definition as described in AliasForGeometryItems can be written directly instead of referencing an AliasName. For the possible choices of BND_entity see below.
