[cvos] Ruby lunch summary

[David Owen]

We started off with Dave South walking us through a wrapper he wrote to 
help use MongoDB.  It allows him to more easily express parent-child type 
relationships, where the linking reference is maintained in the child. 
Doing it this way allows the child data types to be queried without having 
to navigate into the parent data type, but makes querying children based 
on parent more difficult, which his wrapper addresses.

We then moved into a dicussion of test mock libraries, such as Fabricate 
and Faker.
