From 6d751411b7f996c486052c8cbbdbe1e186cebd9f Mon Sep 17 00:00:00 2001
From: lbsa71

Subject: * Added specialization of DatabaseMapper, DataReader and
 ObjectFieldMapper to support LLVector3, LLQuaternion and LLUUID * Added
 PrimitiveBaseShapeTableMapper to show how it's done

NOTE: Nothing actually works yet - this code should be considered more of educational value until it's all wired together
