revision `770e72d2f78361b14f3fe27caea41e5977d3c638`
## List of semantically different functions with contracts
- Class `math.IEEE754rUtils` (converted from Utility/"static" class to allow use of contracts):
- `double min(double[])` and overloads
- `double max(double[])` and overloads
- Class `CharRange`
- `boolean contains(CharRange)`
- Class `util.FluentBitSet`
- `FluentBitSet and(FluentBitSet)` and overloads
- `FluentBitSet andNot(FluentBitSet)` and overloads
- `FluentBitSet or(FluentBitSet)` and overloads
- `FluentBitSet clear()` and overloads
- `boolean get(int)` and overloads
- `boolean isEmpty()`
- `FluentBitSet flip(int)` and overloads
- (TODO) `FluentBitSet xor(FluentBitSet)`
- (TODO) `byte[] toByteArray()` and `byte[] toLongArray()`
- (TODO) `FluentBitSet set(int)`
- (TODO) `int nextSetBit(int)` and `int previousSetBit(int)`
- (TODO) `int nextClearBit(int)` and `int previousClearBit(int)`
## Run Tests
