(
--- received arguments ---
PK_MFACET_t      mfacet,      --- the 'mfacet'

--- returned arguments ---
PK_VECTOR_t      positions[3] --- the 'positions' at the 'mfacet's mvertices
)


This function returns the position vectors at the mvertices of 'mfacet'.


`positions[0]' is the position vector at the mvertex pointed to by the mfin
with mfin_index = 0.
`positions[1]' is the position vector at the mvertex pointed to by the mfin
with mfin_index = 1.
`positions[2]' is the position vector at the mvertex pointed to by the mfin
with mfin_index = 2.
