_D_e_s_c_r_i_p_t_i_o_n:

     Create class SchemeTreeSet accessing ROOT scheme file.

_U_s_a_g_e:

     root.scheme(rootfile = character(0), add.mask = FALSE)

_A_r_g_u_m_e_n_t_s:

rootfile: name of ROOT scheme file, including full path.

add.mask: if 'TRUE' mask information will be included as slot 'mask'.

_D_e_t_a_i_l_s:

     An S4 class 'SchemeTreeSet' will be created, serving as R wrapper
     to the  'ROOT' scheme file 'rootfile'.

_V_a_l_u_e:

     A 'SchemeTreeSet' object.

_N_o_t_e:

     Use this function to access the 'ROOT' scheme file from  new R
     sessions to avoid creating a new 'ROOT' scheme file for every R
     session.

     Do not set 'add.mask=TRUE' for exon arrays unless you know that
     your computer has  sufficient RAM.
