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

     Obtains the block ranges (subranges, usually exons) from an
     object, such as a 'RangedData' imported from a BED file.

_U_s_a_g_e:

     blocks(x, ...)

_A_r_g_u_m_e_n_t_s:

       x: The instance from which to obtain the block/exon information.
          Currently must be a 'RangedData', presumably imported with
          'import.bed'. 

     ...: Additional arguments for methods

_D_e_t_a_i_l_s:

     For the 'RangedData' method, there must be two columns in 'x':
     'blockStarts' and 'blockSizes', each field of which should be a
     comma-separated list of block starts and widths, respectively.
     This comes from the BED specification.

     information.
