Implement sorting

[jsgm]

Hello,

It would be a good idea to have the possibility of sorting the different FindAll() results.

In order to don't make the code complex, here are a few simple ideas for sorting results numerically and alphabetically that would be useful to implement: db.Query("todos").Where(c.Field("completed").Eq(true).And(c.Field("userId").In(5, 8))).FindAll().SortAsc("userId") and SortDesc db.Query("todos").Where(c.Field("completed").Eq(true).And(c.Field("userId").In(5, 8))).FindAll().Sort("userId", 1) or -1
