Ge.Matrix direct constructor

[gswifort]

It would be useful to be able to create an object like Ge.Matrix3d directly from a numpy array or just a list of lists.

matrix = Ge.Matrix3d(
    [
        [1.0, 0.0, 0.0, 0.0],
        [0.0, 1.0, 0.0, 0.0],
        [0.0, 0.0, 1.0, 0.0],
        [0.0, 0.0, 0.0, 1.0],
    ]
)

I could not make it a constructor and have it generic, so I added a static method that should take any iterable, hope this is okay

        mat1 = Ge.Matrix3d.kIdentity
        mat1.setToRotation(0.785398, Ge.Vector3d.kZAxis)
        mat2 = Ge.Matrix3d.fromCollection(mat1.toTuple())
        mat3 = Ge.Matrix3d.fromCollection(mat1.toList())
        print(mat2 == mat1 == mat3)
        print(mat1, mat2, mat3)

actually, I can

       mat1 = Ge.Matrix3d.kIdentity
        mat1.setToRotation(0.785398, Ge.Vector3d.kZAxis)
        mat2 = Ge.Matrix3d(mat1.toTuple())
        mat3 = Ge.Matrix3d(mat1.toList())
        print(mat2 == mat1 == mat3)
        print(mat1, mat2, mat3)

        mat1 = Ge.Matrix2d.kIdentity
        mat1.setToRotation(0.785398)
        mat2 = Ge.Matrix2d(mat1.toTuple())
        mat3 = Ge.Matrix2d(mat1.toList())
        print(mat2 == mat1 == mat3)
        print(mat1, mat2, mat3)

        mat1 = Ge.Matrix3d.kIdentity
        mat1.setToRotation(0.785398, Ge.Vector3d.kZAxis)
        #numpy
        my_matrix = np.array(mat1.toList())
        mat2 = Ge.Matrix3d(my_matrix)
        print(mat2, mat1 == mat2)

((0.7071068967259818,-0.7071066656470943,0,0),(0.7071066656470943,0.7071068967259818,0,0),(0,0,1,0),(0,0,0,1)) True
