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

     Plot a histgram of the expression levels of one or more genes
     distribution at a time  across total experiments.

     EachGeneDataDistView(begin, end, expr.matrix)

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

   begin: the beginning gene number to plot

     end: the ending gene number to plot 

expr.matrix: a microarray expression matrix object with rows containing
          a gene expression  levels across multi-experiment while
          columns denoting expression levels of all genes contained in 
          one microarray slide. 

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

     View a gene expression level distribution within a total
     microarray experiment data set. Normally, we could perform further
     statistical test and find it is a normal distribution with
     'u=mean(vec),S=var(vec)', vec is the expression vector of a
     specified gene.

_V_a_l_u_e:

     No value returned.
