v1.2.5: fix bug found by Michael J.
Clean global namespace in unit2.js

v1.2.5 was a bugfix release. One of the bugs could have been caught had
unit2.js been more careful about maintaining a global namespace. This
new version of unit2.js ensures that global variables are deleted from
the global namespace after each block of unit tests.
Further improvements and tweaks to unit2.js
Rewrite of point wise functions and bugfix

This was triggered by a bug discovered by Dave Wybiral with
numeric.diveq([[1,2],[3,4]],2). This is now fixed.
