Creates an analytic model for the Munk profile, an idealized representation of a deep sound (SOFAR) channel.
The Munk profile is defined as:
z' = 2 * (z-z1)/B ;
c(z) = c1 * (1.0 + e * (z'-1.0+exp(-z'))) ;
where: z = depth below the ocean surface (positive direction down), z1 = depth of the deep sound channel axis, B = depth scaling factor, c1 = sound speed on the deep sound channel axis, e = perturbation coefficient, c(z) = speed of sound as a function of depth.

Build Munk profile from its component parts.
Default to the profile parameters defined in Jensen, Kuperman, et. al.
axis_depth | Depth of the deep sound channel axis (meters). |
scale | Depth scaling factor (meters). |
axis_speed | Sound speed on the deep sound channel axis (m/s). |
epsilon | Perturbation coefficient. |
attmodel | In-water attenuation model. Defaults to Thorp. The profile_model takes over ownship of this reference and deletes it as part of its destructor. |

Compute the speed of sound and it's first derivatives at a series of locations.
location | Location at which to compute sound speed. |
speed | Speed of sound (m/s) at each location (output). |
gradient | Sound speed gradient at each location (output). |
