For once in my life it looks like I properly interpreted something in 
Wikipedia and actually wrote the code to implement the psuedo-code on 
their page.

Not only that, but based on what the psuedocode was saying, I properly 
surmised how to interpolate the resulting spline functions for each 
interval.

Well, of course a spline is easy. Right?

I just wish I knew a bit more of the underlying theory of how the 
coefficients were calculated.

The article speaks of derivatives, so calculus must be involved. I'm 
gathering that the formulae in the algorithm were probably found by 
applying calculus to a 3rd order polynomial.
