"Backend framework" for creating controller-based backend.
For now server
struct from lib can be use only in static context like this:
```
lazy_static! {
static ref SERVER: ApiServer = ApiServer::new(
ApiSettings::new("127.0.0.1", "4444", 2048),
vec![Box::new(UserController::new(
"mongodb://localhost:27017",
"mydb",
"users",
))]
);
}
fn main() { SERVER.start(); } ```
