no, flex-algo is a single application, it's not a mechanism to create 
new applications. The fact that you can create many constraints 
topologies using flex-algo, does not mean these should be considered as 
different apps. You have to put and keep clear borders at clear places. 
We have them defined by ASLA and by base flex-algo draft.
