     These functions can be used to make copies of environments, or to
     get/assign all of the objects inside of an environment.

_U_s_a_g_e:

     copyEnv(oldEnv, newEnv = new.env(hash=TRUE, parent =
     parent.env(oldEnv)), all.names=FALSE)
     listLen(list)
     l2e(vals, envir)

_A_r_g_u_m_e_n_t_s:

  oldEnv: An environment to copy from

  newEnv: An environment to copy to.  Default is a new environment with
          the same parent environment as oldEnv.

   envir: An environment to get/set values to

    vals: A named list of objects to assign into an environment

all.names: Whether to retrieve objects with names that start with a
          dot.

    list: A list

_D_e_t_a_i_l_s:

     'listLen': This function returns a vector of the same lenght as
     the list containng the lengths of each element of the supplied
     argument.

     'l2e': This function takes a named list and assigns all of its
     elements into the environment (using the names to name the
     objects).

     'copyEnv': This function will make a copy of the contents from

     'oldEnv' and place them into 'newEnv'.
