/** If one were to call any of these other methods to get a parse tree for some input sentence
 * with the -outputFormatOptions flag of "lexicalize", they would receive their parse tree,
 * in the -outputFormat of their choice, with every leaf marked with it's head word.
 * This function does exactly that on an existing parse tree.
 * NOTE that this WILL re-lexicalize a pre-lexicalized tree, so don't pass in a tree that
 * has been lexicalized and expect to get back the same thing as what you passed in.
