the class Utils method genRewriters.

/**
 * Generates rewriters based on the list of names of rewrite tables.
 * If a name does not resolve to a rewrite table then generates null.
 * If the given list is null, then the default rewriter is returned (currently at most one).
 * Passing an empty list effectively turns off rewriting.
