They they should be added
@autneticated and @unauthenticated are defined in common.py
The @unauthenticated decorator automatically applys fixtures: db, auth,
session, T. exposes the action with user /{function_name} and defaults to
template {function_name}.html (very much like web2py does)
@authenticated is the same but requires login.
@authenticated.button("click me")
def f(a,b,c): print(a,b,c)
crate a button factory f which you can embed in code with [[=f(1,2,3)]] it
generates a <button onclick="....">click me</button> than when clicked
calls via ajax POST the function f defined in python and passes a=1, b=2,
c=3.
Notice that this API is still work in progress. Works but it is not
documented because we may change it.
