/**
 * For a CIDFont the width array, there are two formats of width array :
 * <UL>//  w  w  w .j a  v a 2  s  .  c  om
 * <li>C [W1...Wn] : C is an integer specifying a starting CID value and the
 * array of n numbers specify widths for n consecutive CIDs.
 * <li>Cf Cl W : Defines the same width W for the range Cf to Cl
 * </UL>
 * This method gets a linked hash map of width where the key is a CID and the
 * value is the Width.

 * @return
