Detailed Description

Quaternion class that supports pymavlink's Vector3 and Matrix3

Usage:
    >>> from quaternion import Quaternion
    >>> from rotmat import Vector3, Matrix3
    >>> m = Matrix3()
    >>> m.from_euler(45, 0, 0)
    >>> print(m)
    Matrix3((1.00, 0.00, 0.00), (0.00, 0.53, -0.85), (-0.00, 0.85, 0.53))
    >>> q = Quaternion(m)
    >>> print(q)
    [ 0.87330464  0.48717451  0.          0.        ]
    >>> print(q.dcm)
    Matrix3((1.00, 0.00, 0.00), (0.00, 0.53, -0.85), (-0.00, 0.85, 0.53))
    >>> v = Vector3(0, 1, 0)
    >>> v2 = q.transform(v)
    >>> print(v2)
    Vector3(0.00, 0.53, 0.85)
