  x = value to find the membership to the fuzzy set
  s = f(x) = SureFactor fuzzy value of the membership

  before l0 s = f(x) = 0 = not member
  between l0 and l1 s = f(x) = linearly grow from 0 to 1 = from non member to full member
  between l1 and r1 s = f(x) = 1 = full member
  between r1 and r0 s = f(x) = linearly grow from 0 to 1 = from non member to full member
  after r0 s= f(x) = 0 = not member
