Miscellaneous on OCaml vectors

Function: is_positivity_constraint : t -> bool

Tell wether the vector is the positivity constraint as does vector_is_positivity_constraint.

Function: is_strictness_constraint : t -> bool

Tell wether the vector is the strictness constraint as does vector_is_strictness_constraint.

Function: is_dummy_constraint : t -> bool

Tell wether the vector is the positivity or the strictnes constraint, as does vector_is_dummy_constraint.
