[Bf-codereview] N-Dimensional Vectors for Blender Mathutils (issue 5482043)

[TrumanBlending at gmail.com]

Reviewers: bf-codereview_blender.org,

Description:
This patch adds the ability to use arbitrary sized vectors from
mathutils. Currently vectors are only of size 2, 3 or 4 since they are
generally restricted to geometric applications. However, we can use
arbitrary sized vectors for efficient calculations and data
manipulation.
