Composite C1 sample codes/pages

I need to learn how Composite C1 does the things. Due to lack of docs, active users etc I decided to post a project which one covers the basics (or not) of Composite C1 that I wonder. C1 docs cover many great things except how end user adds data. For example; how can I add blog post without entering C1 console. I need to create blog entry page, but how? I also manage the blog, list/delete/etc. Many users find C1 console complex. I need to isolate the user from the console. I also want to see data items in C1 console. * Usage of C1 internal database: - Add/remove/update/list/etc the things both at C1 console and end user pages. Ajax WebAPI would be nice. * Usage of external database: - Add/remove/update/list/etc the things both at C1 console and end user pages. Ajax WebAPI would be nice.
