_D_e_s_c_r_i_p_t_i_o_n:

     A driver function for 'Sweave' which will provide the user with
     code chunks from a vignette file within R.  Functionality is very
     similar to that provided by 'Stangle' except that an R object is
     returned as opposed to the chunks being written to a file.

_U_s_a_g_e:

     tangleToR()

_V_a_l_u_e:

     An object of type 'chunkList' is returned, which contains the code
     chunks from the vignette file.
