Skip/Limit criteria

[gamedolphin]

Would be useful to have a skip and limit criteria for number of documents returned by FindAll.

Thank you for this suggestion. I think that I will add a Limit() method on the Query object :-)

@gamedolphin, the last commit (5a5de33) adds a Limit(n int) method which allows to limit the output of FindAll() and Count().

You can give a look at the TestLimit function to see an example of usage. Before closing the issue, I wait for your feedback.

What do you think about directly returning the document instead an array if Limit(n int) is 1?

[ostafen]

To achieve this, the FindAll() function should return an (interface{}, error). This means you should make additional check and conversion to get the actual type (slice or Document), also making the API not backward compatible.
However your idea is interesting and could be achieved by a separate FindFirst() function, returning a (*Document, error).
We could open a separate issue for this :=)

@jsgm I added the FindFirst method with the last commit 59c3127
