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

     S4 class implementation of irregularly spaced time seires. The
     class implements Arith methods using date matching, union,
     intersection, and other time series methods.

     Class '"matrix"', from data part. Class '"structure"', by class
     "matrix", distance 2. Class '"array"', by class "matrix", distance
     2. Class '"vector"', by class "matrix", distance 3, with explicit
