Excessive parentheses only make the expressions hareder to read.

Replace use of float by double.

All values in a quaternion are declared double, let's not lose precision on
platforms where double is larger than float.

Simplify several functions by replacing the body with one-line calls to the
constructor. Furthermore, pass Quaternion arguments by reference to avoid
excessive copying.

Quaternion needs the definition of a matrix. Include it.

Fix conversion of impure rotation matrices to quaternions

The test for the largest element in the matrix diagonal was reversed, which
resulted in taking the square root of a negative value for matrices with
determinant less than zero.

Add "const" to non-mutating Vector, Quat methods

Also adds some clarifying documentation, since the quat->euler axis
conventions are a bit surprising.
