As I guess you already knew, Angle normalizes to -PI, PI (as it should 
be), so if you want the whole range you need to test against [-PI,PI]

My guess would be that, if you really want to handle that case, you will 
have to create a new class AngleRange that is initialized from 
non-normalized angles, e.g.

range = Angle::Range(0, 2*PI) => this internally normalizes to -PI,PI
range.testInRange(angle)
