Trevor Parscal	8ce7fd0c85	Fixed length calculations and added tests for node tree ... Image nodes are leafs, so providing an empty array to their children/length "contents" constructor argument ends up setting the numeric length to [], which casts to an empty string in arithmetic, causing all further calculations to be concatenations instead of additions.
