_D_e_s_c_r_i_p_t_i_o_n:

     This function generates grid and spot matrix coordinates from
     ranges of rows and columns for the grid and spot matrices. Spots
     on the array are numbered consecutively starting from the top left
     grid and the top left spot within each grid.

_U_s_a_g_e:

     maCompCoord(grows, gcols, srows, scols)

_A_r_g_u_m_e_n_t_s:

   grows: numeric vector of grid rows.

   gcols: numeric vector of grid columns.

   srows: numeric vector of spot rows.

   scols: numeric vector of spot columns.

_V_a_l_u_e:

     a matrix of spot four-coordinates, with rows corresponding to
     spots and columns to grid row, grid column, spot row, and spot
     column coordinates.
