vb_get_max_med_ratio

 Estimate mean amplitude by using histgram for outlier exclusion
 and calculate amplitude/mean ratio to find bad channel & trials
 amplitude/mean ratio using Median can be also calculated
   [ymax, med] = vb_get_max_med_ratio(X)
 X(t,n)  : signal at time t & n-th trial         [Tsampla x Ntrial]
 ymax(n) : amplitude/median ratio for each trial [1 x Ntrial]
         = max_t (abs(X(t,n))) 
 med(n)  : median of abs(X(:,n))
