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