// method: project_phones_cc
//
// arguments:
//  Train_Link_node** wdmarker : (input) marker positions in word-level trace lists
//  Train_Link_node** phmarker : (input) marker positions in phone-level trace lists
//  Train_Link_list** token_list : (input) lists of all tokens
//  Train_Phone** phones : (input) all phone models
//  Train_Link_list* treelist : (input) list of active lexical trees
//  Train_Lattice* lattice: (input) the lattice for this application
//  int_4 num_mono : (input) number of monophones
//  int_4 ph_size : (input) size of phonetic context
//  int_4* ph_map : (input) the phone map
//  int_4*& wd_active : (output) list of active words
//  int_4& wd_numact : (output) number of active words
//  int_4*& ph_active : (output) list of active phones
//  int_4& ph_numact : (output) number of active phones
//  int_4*& ngen : (input) number of new traces generated
//  float_8& max_score : (input) the maximum path score so far
//  logical_1 mlf_mode : (input) the mlf mode flag
//
// return: a logical_1 indicating status
//
// this method loops over all word and phone level traces, projects
// them onto new phones to create state-level traces and generates
