* <b>Purpose</b>: Abstract superclass for Large &amp; Small projects in Employee Demo
* <p><b>Description</b>: Project is an example of an abstract superclass. It demonstrates how class inheritance can be mapped to database tables.
* It's subclasses are concrete and may or may not add columns through additional tables. The PROJ_TYPE field in the
* database table indicates which subclass to instantiate. Projects are involved in a M:M relationship with employees.
* The Employee classs maintains the definition of the relation table.
