Purpose

---

  This function computes centered Voigt profiles. It is a wrapper to the
  builtin IDL VOIGT routine, which uses a somewhat confusing variable
  convention. The Voigt function implemented here is a stright
  convolution of a Gaussian with a Lorentzian.

Inputs

---

  x: The abcissa values. The profile will be centered on x=0. Scalar
    or vector.
  sigma: The width of the Gaussian part of the profile. Scalar or
        vector
  gamma: The width of the Lorentzian part of the profile. Scalar or
        vector

Outputs

---

  The voigt profile with the specified sigma, gamma, evaluated at x.
