feat: Implement Vector type (#28)

The Vector type is simply a generic type for built-in JavaScript Arrays. The parameter type is the type of all of the entries of the Array. The Vector type also supports inhomogeneous arrays by using the special type `Unknown` as the argument type, but note that when computing with inhomogeneous arrays, method dispatch must be performed separately for every entry in a calculation, making all operations considerably slower than on homogeneous Vector instances.

Note also that arithmetic operations on nested Vectors, e.g. `Vector(Vector(NumberT))` are defined so as to interpret such entities as ordinary matrices, represented in row-major format (i.e., the component `Vector(NumberT)` items of such an entity are the _rows_ of the matrix.
