Support n-dimensional vectors

[almstrand]

Can a new Vector class be added that represents a vector of arbitrary length?

It seems the current implementation of classes Vector2, Vector3, and Vector4 can be generalized to form a new class VectorN, which would also implement Vector.

Clearly, 2, 3, and 4 dimensional vectors are sufficient for many applications. However there are applications where this restriction becomes prohibitive. The options for overcoming this restriction include creating another pub package, or a custom implementation in the application itself; neither of which promotes re-use, nor settling on a common package for solving a very common problem.

As an example, pub package math_expressions has the set goal of "[...]supporting real, vector and interval evaluations of mathematical expressions." As the package depends on vector_math it is currently limited to evaluating expressions involving up to 4-dimensional vectors. An issue has been filed to look into options for eliminating this limitation. One of the options is for math_expressions to add a class that implements Vector and represents vectors of arbitrary length, but it seems such a class would better belong invector_math to promote standardizing on a singe package for representing vectors of all types.

Adding general size matrix / vector types to vector_math could happen but probably won't happen anytime soon because it is a lot of work.
