Purpose:
!>
!> IZMAX1 finds the index of the first vector element of maximum absolute value.
!>
!> Based on IZAMAX from Level 1 BLAS.
!> The change is to use the 'genuine' absolute value.
!> 
Parameters
[in]N
!>          N is INTEGER
!>          The number of elements in the vector ZX.
!> 
[in]ZX
!>          ZX is COMPLEX*16 array, dimension (N)
!>          The vector ZX. The IZMAX1 function returns the index of its first
!>          element of maximum absolute value.
!> 
[in]INCX
!>          INCX is INTEGER
!>          The spacing between successive values of ZX.  INCX >= 1.
