```
public Unit getUnits(String specification)
```
    Get units from a string specification.
    Parsing is performed only the first time a specification is encountered, so the cache speeds up cases where the same units is encountered many times (for example when parsing CCSDS messages with many entries).
    
    Parameters:
    
    specification - units specification (may be null)
    
    Returns:
    
    parsed units (Unit.NONE if specification is null)
