- renamed Z -> Int
- made Int ops methods on *Int
- "install" assembly routines dynamically
- replace mulVW functions with mulAddVWW
  of equivalent performance but symmetric functionality
  to divWVW
- implemented scanN

status:
- need mulNN (trivial)
- need division/modulo after which the set of
  elementary operations is complete
- to/from string conversion working

- implemented low-level operations on word vectors
- implemented corresponding amd64 assembly routines for word vector operations
- implemented first set of operations on unsigned integers
- implemented first set of operations on signed integers
- implemented systematic test cases  for each data type
