#11 Implement "add" method w/o conjunction

[Will Hoover]

When adding a SearchCriterion to a SearchCriteria there is no "add" method w/o a conjunction (and it cannot be null). For example:

myKeyListDTC.getCriteria().addCriterion(SearchCriteria.Conjunction.OR, myCriterion);

... may be the only criterion added or the last criterion added. This would imply that there is a conjunction that is not being used.
