Return a pointer to a specific tree in a trees struct plus pointers to its face_neighbor and tree_to_face arrays.

Parameters:

trees – [in] The trees structure where the tree is to be looked up.
ltree_id – [in] The local id of the tree.
face_neigh – [out] If not NULL a pointer to the trees face_neighbor array is stored here on return.
ttf – [out] If not NULL a pointer to the trees tree_to_face array is stored here on return.

Returns:

A pointer to the tree with local id tree.
