stashing this here for now
A nearly complete restructuring of code.

  * Use sectionify to allow for building of packages optimized for v1() and v4()
  * Switch to nodeunit for testing
  * Remove benchmark test (this code runs fast enough that speed differences typically aren't that important)
  * Remove perf test comparisons against other frameworks (again, not that interesting)
  * Remove testing of random number quality - that type of testing is way outside the scope of this module.
