/**
 * Parsing component for transliterator IDs.  This class contains only
 * static members; it cannot be instantiated.  Methods in this class
 * parse various ID formats, including the following:
 *
 * A basic ID, which contains source, target, and variant, but no
 * filter and no explicit inverse.  Examples include
 * "Latin-Greek/UNGEGN" and "Null".
 *
 * A single ID, which is a basic ID plus optional filter and optional
 * explicit inverse.  Examples include "[a-zA-Z] Latin-Greek" and
 * "Lower (Upper)".
 *
 * A compound ID, which is a sequence of one or more single IDs,
 * separated by semicolons, with optional forward and reverse global
 * filters.  The global filters are UnicodeSet patterns prepended or
 * appended to the IDs, separated by semicolons.  An appended filter
 * must be enclosed in parentheses and applies in the reverse
 * direction.
