SIMPLE IQueryable implementation for the MongoQuery

the mongo interface does not support all the functionality that Linq can provide.

Planned support

mongo query object (done)

directly support an object which support the Mongo Query object

Selector (IDictionary<string,object>)
Skip (long or int)
Take (long or int)
Sort by (IEnumerable<IDictionary<string, ordery>>)
index (string)

Query<T> (done)

the implementation needs to take into account the limited power of the mongo statement. which means we may only be able to statisfy only part of the linq query, allowing the rest to be executed in memory

Query<T>(string index /optional) -> returns IQueryable, note take into account base/inherited classes done
Where() -> each one becomes an and'ed part of the selector done
OrderBy -> done
Take Skip -> can be converted, as long as it is not after a Select done
Index -> selecting an index. basic done
string -> startswith, endwith, equals and contains - done
collections -> collection.Any(x.Name) and x.Names.Any(x=> x == "dave") done

//need to list interactions for each, will try and use tests to help show this.

Mapping (done)

this is a first time, basically if we are to support Query<Animal>().Take(10).ToList(), we will need to find all the objects which inherit Animal.

note the inital idea is to support a way to scan for types and auto set them up. but also allow the user to specifiy nicely what is the Id and Rev fields. thats the current scope.
