App now uses separate add_session to insert data into it

improved the hub and spoke-ish model of App by making it more clear
that its components have specific responsibilities, which App then
glues together.

moved timermanager to App to seperate the invoker from receiver so we
can eventually add interactivity

also fixed the using namespace std error from a while ago
