edu.uga.galileo.voci.bo.Role
A basic business object for holding role information.

For various Reflection requirements, all variable names should map to database column names, with a slight twist: Whenever an underscore is encountered in the db column name, it should be excluded from the variable name here, but the following character should be capitalized. If the column name is 'first_name', for example, the variable here should be 'firstName'. Getters and setters should be named accordingly. @author Mark Durant @author Charles King @version 1.0
