  This will lesion incoming links to the groups in one of three ways. The
  proportion, which defaults to 1.0, gives the likelihood that each link will
  be affected. It is not guaranteed that exactly (100 x proportion)% of the
  links will be affected. If a link type is given, only links of that type
  will be affected.

  With no value or range, the links will be permanently deleted.

  With just a value specified, the link weights will be set to this value.
  Typically a value of 0.0 would be used.

  With a positive range and boolean multiplicative and gaussian values
  specified, noise will be introduced in the weights of affected links. See
  the help for the command _n_o_i_s_e_T_y_p_e for an explanation of these parameters.

  When the weight of a link has been changed with this procedure, it is not
  possible to restore the previous value. Therefore, be sure to _s_a_v_e_W_e_i_g_h_t_s
  before lesioning the links.

  If you may want to recreate the exact same lesion again, be sure to seed
  the random number generator before lesioning and record the seed value.

  EEXXAAMMPPLLEESS

  To remove 50% of all incoming connections to the group "output":

        lens> lesionLinks output -p 0.5

  To zero all the bias connections to the group "output":

        lens> lesionLinks output -v 0 -t bias

  To multiply the weights of all links by gaussian noise with a standard
  deviation of 0.1:

        lens> lesionLinks * -r 0.1 -m
