/**
 * <b>Purpose</b>:         Abstract superclass for Large & 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.
