Grouping files in Web Matrix

I am using Web Matrix with v.1.1 of the framework. I don't see a concept of a project or solution in Web Matrix, so here's my problem.

I have one aspx file that wants to use a class file called "SkillSet.vb". Skillset.vb in turn wants to use another class file "Skill.vb". How do I group them all together if I am using Web Matrix?
