Detailed Description

This file contains basic filtering operators for getting a list of instances out of the database. This works by overloading the operators to take either a DBField<T> or the wrapper dbField that is used to specify a field by name instead of instance. This completely replaces the 'example' parameter. It is now possible to specify filter clauses for a query in c++ syntax like this:

db.getList(seq, dbField("id") > 20 && dbField("x") < 30);
