Oblique Spherical Triangle toolbox

This toolbox can solve any of the 6 possible subproblems associated with an oblique spherical triangle, when only 3 of the 6 angles are known.
The toolbox basically is an implementation of the set of tools developed in [Wertz, 2001], which aimed to fully automize the procedure and do away with the need of user intervention.

EXAMPLE:

[b1, c1, C1, b2, c2, C2] = aas(A, B, a)

gives both solutions for the sides b and c and the angle C, when given angles A, B and side a. This particular problem can be called the Angle-Angle-Side problem, hence the name.

Both degrees and radians are implemented, the difference is indicating by appending a 'd' to the function name. The above example expects and returns radians, whereas

[b1, c1, C1, b2, c2, C2] = aasd(A, B, a)

expects and returns degrees.
