Specialisation of Feature for integral types.
It is a valid operator to compare an int to a float, but the generic version of these operators in the base class will first cast input float to an int, then compare that. In some cases the comparison will be incorrect because of rounding the float. e.g. int x=5; float y=5.5; bool result = x<y; would be wrong because y first gets converted to int 5.
To solve this, we provide specialised comparison operators for integral type and double. Note that the opposite specialisation in which the Feature_type is floating_point is not necessary
