Add vector constraints

[Cargopal]

Trying to add a vector constraint to my optimization problem, I came to one error when using the syntax: inequality_constraint!(opt, m, (c,u,g) -> constraints(c,u,g,p), tol )

I checked the code and found a little bug; in line 476 is written $cf(o, f, fill!(Cdouble(tol), m))

while it should be

$cf(o, f, fill(Cdouble(tol), m))

without the exclamation mark
