importing a module ( file ) from the same directory is only possible with the relative import syntax
however, I prefer the more consistent "from OCC.Display import X" syntax

finally, `apply` is no longer a keyword in py3k, so that's updated to unpacking the arguments form a tuple
Merge pull request #26 from jf---/jf/py3k-import-relative-path-display

import OCC.Display from py3k fails ( relative import, missing apply function )
Added 2 more examples
PEP8 improvements; removed menu item for atomic examples ; misc fixes/improvements
