/**
 * Converts an array of characters representing hexadecimal values into an

 * length of the passed array, as it takes two characters to represent any
 * given byte. An exception is thrown if the passed char array has an odd
 * number of elements.
 *
 * @param data An array of characters containing hexadecimal digits
 * @return A byte array containing binary data decoded from
 *         the supplied char array.
 * @throws IllegalArgumentException if an odd number or illegal of characters
 *                                  is supplied
