These vectors support operations to determine the similarity between two documents or a document and a query. Normally no parameters are required for initializing a vector, but in the case of loading a previously dumped vector the raw elements can be provided to the constructor. For performance reasons vectors are implemented with a flat array, where an elements index is immediately followed by its value. E.g. [index, value, index, value]. TODO: consider implemetation as 2-tuples. This allows the underlying array to be as sparse as possible and still offer decent performance when being used for vector calculations.
