Functions

func ApplyMiddleware

func ApplyMiddleware(h http.HandlerFunc, middleware ...Middleware) http.HandlerFunc

ApplyMiddleware will apply all middleware, the last arguments will be the outer wrap for context passing purposes

func GetID

Middleware is what all middleware functions will return

func Logger

SetID updates context with the id then increments it
