docs: Validate the isotope pattern of this IMolecularFormula. Important, first
  you have to add with the {@link #setParameters(Object[])} a IMolecularFormulaSet
  which represents the isotope pattern to compare.
  
  @param formula   Parameter is the IMolecularFormula
  @return          A double value meaning 1.0 True, 0.0 False
