Make a method that creates a copy of the Player with erasing the relevant
fields:
type Player struct {
Id bson.ObjectId `json:"id,omitempty" bson:"_id,omitempty"`
CustomField string `json:"customField,omitempty"
bson:"customField,omitempty"`
}
func (player Player) Frontend() Player {
player.CustomField = ""
return player
}
