Set the condition tree of the promotion. The condition tree is a hierarchical structure that defines the conditions under which the promotion will be applied. The condition tree is composed of branches, each of which contains a condition that must be met for the promotion to be applied. In order to connect branches into a tree, each branch has a unique id based on its index in the array, and an optional parent field with the index of the parent. Note that branches may only point to parents in LOWER index than themselves.
