Congratulation ;)

Not sure; this is a "basic" example, there is always such an example here

http://doc.cgal.org/latest/Combinatorial_map/index.html#title22

for tetrahedra, and the function make_tetrahedron exists in CMap and LCC.

You can either use the undocumented class 
Linear_cell_complex_incremental_builder_3, or make your own function by 
hand. Have a look at the function sew3_same_facets in Linear cell 
complex which does a similar process but for faces in 3D.
