Do not modify opts in base.js, these may be globals.

[toots]

Modifying options passed to findOne and the like can be potentially dangerous. Here's an example:

# What to fetch for a radio
radiosParams =
  order   : [ "name" ]
  only    : [
    "id", "name", "token", "website",
    "title", "artist", "genre", "description",
    "longitude", "latitude"
  ]
  include : {
    streams : {
      only : [ "id", "format", "url", "msg" ]
    }
  }

@ Wrappers
getRadios = (param, fn) ->
  Radio.find param, radiosParams, fn

getRadio = (param, fn) ->
  Radio.findOne param, radiosParams, fn

In one call getRadio then all subsequent calls to getRadios have only one result, due to the fact that limit: 1 gets added to radiosParams..
