  - compare
```
rx.Observable<HalDifference> compare(HalComparisonSource expected,
                                     HalComparisonSource actual,
                                     HalComparisonStrategy strategy)
```
    Recursively crawl and compare the linked and embedded HalResources from two different HAL API entry points.
    
    Parameters:
    
    expected - a HalComparisonSource that provides the ground truth for the comparison
    
    actual - a HalComparisonSource that provides the resources that should be compared with the expected resources
    
    strategy - can be implemented to limit the crawling and comparison depth (e.g. ignore specific link relations)
    
    Returns:
    
    an Observable that emits one HalDifference object for each difference that was detected
