[Nitro] Og test cases and specs

[George Moschovitis]

Dear devs,

Og needs a strong and up-to-date suite of specs. The repo currently
contains many out-of-date tests. I need your help to rectify this.
Here is a plan:

* the tests must be updated:
    - require paths fixed
    - property converted to attr_accessor
    - ' converted to "
    - use correct name spaces.
* Test cases must pass
* Test cases should be converted to specs
* specs need refactoring.

Since many people on this list use Og and care about this library, I
would expect to see some volunteers for this work.

thanks,
George.
