Address Todo items in AzimuthElevationToCartesianTransform

[hjmjohnson]

Description

AzimuthElevationToCartesianTransform

• \todo Is there any real value in allowing the user to template
• over the scalar type? Perhaps it should always be double, unless
• there's a compatibility problem with the Point class.
• \todo Derive this class from TransformBase class.
• Currently, this class derives from AffineTransform, although
• it is not an affine transform.
• \todo Add a figure in the documentation that informs the formulas used in this class
• that are used to transform Cartesian to azimuth-elevation-radius

Expected behavior

Noted todo items should be removed from code base.

What is this being blocked by?

[hjmjohnson]

That was a mistake.

One thing that might be worth noting: most of the code of AzimuthElevationToCartesianTransform is duplicated in PhasedArray3DSpecialCoordinatesImage.
