+ * extract format specifiers and sends those specifiers to a handler function,
+ * which then, based on conversion type part of the specifier, calls the
+ * appropriate function to handle the specific conversion.
+ * For specific functionality implemented, look at formatRe below, or look
+ * at the tests.
