insert_cell_1_in_cell_2 ( CMap& cm, typename CMap::Dart_handle dh1, typename CMap::Dart_handle dh2)

Inserts a 1-cell in the 2-cell containing dh1 and dh2. Returns β₀(dh1), a handle on one dart belonging to the new 1-cell.

Precondition:

is_insertable_cell_1_in_cell_2<Map>(cm,dh1,dh2).
See example in Figure 27.13.
If 2-attributes are non void, Attribute_type<2>::type::On_split(a,a') is called, with a the original 2-attribute associated with dh and a' the new 2-attribute created during the operation.
