Moved the IBaseDAO and BaseDAO classes to their own packages and out of learning design. This interface and class may be used as the basis for any Hibernate DAO in the system - it isn't compulsory but it is a handy way of getting functionality. If we are going to be using it all over the place, having the classes in the learning design package is not a good idea.
Updated BasicToolVO to match the current Tool object, and added an interface to BasicToolVO. Now the call in lLamsToolService which allows a tool to access its own record in the lams_tool table refers to an interface (IToolVO) rather than a POJO. The code still passes a BasicToolVO to any calling tools, but it is better to refer only to interfaces in a service definition, rather than a concrete class.
