v0.4.1

• The operation \ between Quaternions and Vector now supports every AbstractVector.
• The EulerAngleAxis now stores the vector v using SVector instead of Vector. Notice that the constructors were adapted to accept all AbstractVector. Hence, it is not expected any breakage in old code.
• The conversion between Quaternion and EulerAngleAxis now checks if the Euler angle is 0. In this case, the Euler vector [1;0;0] is used. Previously, a vector with NaN was returned.
