This is intended to be a general utility to find the first sequence of leaf constructs that together constitute a composite construct.  The input leafs aren't assumed to represent a legal construct.
It's also used in `isCompositeConstruct` as well, where I break up the given directive into leafs and check if the "first composite range" is equal to the sequence of leafs.
