 250  *
 251  * - Prefer factory methods over Contructors whenever possible.
 252  *   Don't expose the constructor method unless required.
 253  *
 254  *   e.g. Don't allow the script to construct a "Track" Object directly
 255  *   but do allow to create a "BBT_TIME" object.
 256  *
 257  * - Do not dereference Shared or Weak Pointers. Pass the pointer to Lua.
 258  * - Define Objects as boost:shared_ptr Object whenever possible.
 259  *
 260  *   Storing a boost::shared_ptr in a Lua-variable keeps the reference
 261  *   until that variable is set to 'nil'.
 262  *   (if the script were to keep a direct pointer to the object instance, the
 263  *   behaviour is undefined if the actual object goes away)
 264  *
 265  *   Methods of the actual class are indirectly exposed,
 266  *   boost::*_ptr get() and ::lock() is implicit when the class is exported
