Expose query object from getUsersInRole

[czeslaaw]

Hi

I use your package a lot and it is great. I wonder if you could add possibility to get query object from getUsersInRole function, right before it calls Meteor.users.find.

Something like

_getUsersInRoleQuery(role, group) {
  // same logic as getUsersInRole but returns query object instead of calling Meteor.users.find
}

then getUsersInRole would be just

getUsersInRole(role, group) {
  return Meteor.users.find(_getUsersInRoleQuery(role, group));
}

It would be useful is scenarios:

• extending query with additional fields
• use as query in update, remove or findOne
• use with different find options
• i am not sure but i guess it can be used internally in userIsInRole function

I can do PR but i wonder if you think this is a good idea.

Thanks a lot :)
