The Python math module already has degree() and radian()
functions for conversion.

The idea of having an internal state flag in Euler for setting
units is clever, but seems overly complicated.  If passed as an
argument, you would need to test the Euler obj before you could use
it.  It also becomes One More Thing to keep track of when coding.

You could hide some complexity by creating EulerDegree and EulerRadian
wrapper classes, but then we have 3 classes to manage  rather than one
and we are getting complicated again.

I think the simplest, most consistant solution is to use radians
everywhere.  

If we need to convert to/from degrees for presentation layer things
like a GUI, we can provide our own convenience methods and
constructors in addition to the degrees() and radians() in the math
module.
