SOFA Routines

The SOFA sub-package is meant to be a migration path for those who are already using the C interface package, i.e., the sisl package. This means that SOFA is essentially a drop-in replacement. It also has the potential for checking the accuracy of the C algorithms by replacing the Float64 type with higher precision types such as Float128 or BigFloat and for checking the error propagation of the algorithms.

In addition to that, it has the potential to provide higher performance compared to the C library, particularly when doing calculations of a large number (of order millions) of objects. Having to do a C call on every object incurs a huge overhead and is a signifficant performance hit.
