make sure that the property name are properly resolved regardless if it's a nested property or not

[samirski]

the property name resolution works in the following scenarios as well, regardless if these classes are nested or not:

class Person
        {
            [DocumentProperty(Identifier = IdentifierType.Key)]
            public string Key { get; set; }
            public string Name { get; set; }
            public int Age { get; set; }

            public Address Address { get; set; }
        }

        class Address
        {
            public string Street { get; set; }
            public string City { get; set; }
        }

previously defining an index on Address.Street would create and index on Street which is wrong

db.Advanced.EnsureIndex<Person>(new EnsureIndexData
                    {
                        Type = IndexType.Hash,
                        Unique = false,
                        Fields = new List<string> {
                            //"cell",
                            // or if you dont want use strings
                            db.SharedSetting.Collection.ResolvePropertyName<Person>(x=>x.Address.Street)
                        }
                    });
