Add count method to complement the search method

[xewl]

closes #5

[obuchmann]

Thank you for your PR. Could you please add a test in the OdooTest class.

Things I notice:

Odoo Request classes like Search, SearchRead expect a Domain even though the wrapper methods for them seem to have them nullable.

Seems like there's also more tests to add, outside of this one, even though Count can perfectly be done with the Search Request class on its own, as long as a default/empty Domain is provided instead of null.

By this logic, I also adjusted the ObjectEndpoint class, so the following methods also null coalesce a default empty Domain object, like the model method does, and their Request classes and the Odoo API respectively expect:

• count
• search
• searchRead

I renamed 4 tests that are actually testing the Model way, to include "Model"

• testCount -> testModelCount
• testCountWhere -> testModelCountWhere
• testSearchRead -> testModelSearchRead
• testSearchReadFields -> testModelSearchReadFields

and added 4 new ones:

• testDirectCount
• testDirectCountWhere
• testDirectSearchRead
• testDirectSearchReadFields

These however may need to be split to separate files, as the layer of their use is different (Direct calls vs Eloquent-like).

Hi @xewl, i'm sorry, i have been very busy and had no time to review.

Your PR looks very good! Good point with splitting the tests, we should consider this in a new PR.

Thank you for your contribution!
