A branch is used to simplify multipath management when constructing Chains.
It works just like a normal Chain, except that it calls the asynchronous
decision function and uses it to select between the A and B alternatives,
which are most useful when given as Chains.
@param cond Condition function to use as the branch decision point
@param t Chain/function to execute if the condition is true
@param f Chain/function to execute if the condition is false
