 * @brief  Read in HMMList file
 *
 * HMMList file specifies how the phones as described in word dictionary,
 * or their context-dependent form, should be mapped to actual defined %HMM.
 *
 * In HMMList file, the possible phone names and their corresponding %HMM
 * name should be specified one per line.  The phone name should be put on
 * the first column, and its corresponding %HMM name in the HTK %HMM definition
 * file should be defined on the second column.  If the two strings are
 * the same, which occurs when a %HMM of the phone name is directly defined,
 * the second column can be omitted.
 *
 * When using a triphone model, ALL the possible triphones that can appear
 * on the given word dictionary should be specified in the HMMList file.
 * If some possible triphone are not specified in the HMMList, Julius
 * produces error.
