public static String cache(String s)
```
    Get the string from the cache if possible. If the string has not been found, it is added to the cache. If there is such a string in the cache, that one is returned.
    
    Parameters:
    
    s - the original string
    
    Returns:
    
    a string with the same content, if possible from the cache
  - fromCacheOrNew
```
public static String fromCacheOrNew(String s)
```
    Get a string from the cache, and if no such string has been found, create a new one with only this content. This solves out of memory problems if the string is a substring of another, large string. In Java, strings are shared, which could lead to memory problems. This avoid such problems.
    
    Parameters:
    
    s - the string
    
    Returns:
    
    a string that is guaranteed not be a substring of a large string
  - clearCache
```
public static void clearCache()
```
    Clear the cache. This method is used for testing.
