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

     'aminoacyl' is a list containing the codon counts of 36 genes
     encoding yeast aminoacyl-tRNA-synthetase(S.Cerevisiae).

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

     'aminoacyl' is a list containing the 5 following objects:  

     _g_e_n_e_s is a vector giving the gene names. 

     _l_o_c_a_l_i_s_a_t_i_o_n is a vector giving the cellular localisation of the
          proteins (M = mitochondrial, C = cytoplasmic, I =
          indetermined, CI = cyto and mito).    

     _c_o_d_o_n is a vector containing the codon.

     _A_A is a factor giving the amino acid names for each codon.

     _u_s_a_g_e._c_o_d_o_n is a dataframe containing the codon counts for each
          gene.
