docs: Gets the RelationalOperator performing less than equal to or greater than comparisons to determine whether all
  provided values are less than equal to some upper bound value or possibly greater than some lower bound value.
  
  @param lowerBound the Comparable upper bounded value.
  @param upperBound the Comparable lower bounded value.
  @param <T> the expected Class type for the object used in the less than equal to or greater than comparison.
  @return a RelationalOperator for the less than equal to or greater than comparison.
