+  @class Grid
+  Grid is a logical segment of the game world represented inside TrinIty.
+  Grid is bind at compile time to a particular type of object which
+  we call it the object of interested.  There are many types of loader,
+  specially, dynamic loader, static loader, or on-demand loader.  There's
+  a subtle difference between dynamic loader and on-demand loader but
+  this is implementation specific to the loader class.  From the
+  Grid's perspective, the loader meets its API requirement is suffice.
