A new type of keystonejs ObjectArray (sub object collection)
As people are discussing about keystone issue 153 (https://github.com/keystonejs/keystone/issues/153), Keystonejs users expect to have a sub-collection or sub object list/array.
Mongodb is a new database, which does not like traditional database. We can put sub-object and sub-collection(sub-array) into a table(to avoid confuse you I will keep calling mongodb collections as table). However Keystonejs does not support that, Keystonejs still suggest to use reference to connect to another table.
