+// PiecePool.cpp
+
+// Implements the cPiecePool class representing a pool of cPieces - "parts" of a structure, used in piece-generators
+// A cPiece is a single static part of a structure that can rotate around the Y axis, has connectors to other pieces and knows how to draw itself into the world.
+// The pool manages the pieces and provides lists of its pieces matching criteria, and provides relative weights for the random distribution of pieces.
