Cleanup and example for positioners

Interim progress on fixing up the positioners.
 - Removes margins and setting and implicit size
 - Purges the word 'layout' from the source files
 - Fixes a bug with the grid positioner, it works now
 - Cleaned up the code somewhat.

Also adds some basic examples which demonstrate that it (mostly) works.
Be warned that practically all the comments are woefully out of date.
