Counter example app

[the-moisrex]

Using in-memory SQLite, Views, Beast, Dynamic Router and Query Builder, I would like an example application to see where I'm at.

So with these features you can essentially make a simple website.

TODO:

• Fix beast_view example #159
• Dynamic Router #44
• Create/Alter/Drop/StructReader Query Builder #167
• request body size #190
• Write the example
• Separate the app.hpp and app.cpp files
• Dynamic Traits? #168

I've written a sketch of what it's gonna be as a counter app example. I should come naturally to the developer when they're coding.

There are plenty of features that haven't been implemented yet being used in this counter app even though it's a super simple app.
