This Haskell library implements several small vectors types
Double fields, with seperate types for each size of
vector, and a type class for handling vectors generally.
(Note that although this package is listed in the "graphics"
category, the package itself has no graphics facilities. It
just contains data structures that are useful for graphics
Fixed a stupid bug in
union. Until now, the function could sometimes return gibberish answers. Hopefully this is now fixed.
