parser fails to assign type to logical funtions

[wsmorgan]

code:
function is_equiv_lattice(lat1,lat2,eps)
real(dp), intent(in) :: lat1(3,3), lat2(3,3), eps
logical is_equiv_lattice, err
real(dp) :: lat1inv(3,3), S(3,3)
integer i
is_equiv_lattice = .false.
call matrix_inverse(lat1,lat1inv,err)
if (err) stop "Problem with input vectors in function 'is_equiv_lattice'"
S = matmul(lat1inv,lat2)
if (equal(abs(determinant(S)),1._dp,eps) .and. &
equal(S,nint(S),eps)) is_equiv_lattice = .true.
endfunction is_equiv_lattice

fortpy compile log:

is_equiv_lattice.f90:10.2:

None :: is_equiv_lattice_fpy

This issue is caused by the lack of :: after the logical keyword defining the output type of the function. If we decide that the parser ought to handle the old style of doing it without the ::, we could work at it. But it is a lot simpler to just require it. Let me know what you think.

Making the :: a requirement isn't a big deal, I'll just need to update our older code a bit.
