_D_e_s_c_r_i_p_t_i_o_n:

     A track data object is the result of emu.track().

_F_o_r_m_a_t:


     $_i_n_d_e_x a two columned matrix, each row keeps the first and last
          index of the $data rows that belong to one segment

     $_f_t_i_m_e a two columned matrix, each row keeps the times marks of
          one segment

     $_d_a_t_a a multi-columned matrix with the real track values for each
          segment

_M_e_t_h_o_d_s:

     The following generic methods are implemented for trackdata
     obects.

_N_o_t_e:

     The entire data track is retrieved for each segment in the segment
     list. The amount of data returned will depend on the sample rate
     and number of columns in the track requested.
