/**
 * This is a simple class that walks through the CLDR hierarchy and does 2 things.
 * First, it determines all the places where the CLDR is not minimal: where there
 * are redundancies with inheritance. It generates new files in the target directory.
 * Second, it gathers together all the items from all the locales that share the
 * same element chain, and thus presents a "sideways" view of the data, in files called
 * by_type/X.html, where X is a type. X may be the concatenation of more than more than
 * one element, where the file would otherwise be too large.
