 246  * - Prefer factory methods over Contructors whenever possible.
 247  *   Don't expose the constructor method unless required.
 248  *
 249  *   e.g. Don't allow the script to construct a "Track" Object directly

 251  *
 252  * - Do not dereference Shared or Weak Pointers. Pass the pointer to Lua.
 253  * - Define Objects as boost:shared_ptr Object whenever possible.
 254  *
 255  *   Storing a boost::shared_ptr in a Lua-variable keeps the reference
 256  *   until that variable is set to 'nil'.
 257  *   (if the script were to keep a direct pointer to the object instance, the

 259  *
 260  *   Methods of the actual class are indirectly exposed,
