Investigate possible enhancements to DaoHelpers and AllowedFields

[sleberknight]

The DaoHelpers utility class contains methods to add sorts to SQL queries (or possibly HQL or other similar query languages). It works in conjunction with AllowedFields which is a (very) simple way to define which properties are allowed.

This task is to investigate refactoring and/or redesigning these two classes (and DaoHelpers is a terrible name). For example, instead of having a bunch of static utility methods, would it be "better" to have an instance-based class that works in conjunction with AllowedFields? Or maybe an instance-based class would delegate under the covers to DaoHelpers but present a nicer, more fluent perhaps, interface for callers.
