[Biojava-l] CircularLocation bug fixed

[Schreiber, Mark]

Hi -
 
Thanks to who ever it was who pointed out the CircularLocation bug. It has led to some furious recoding and a plethora of Unit tests such that CircularLocations now behave sensibly with regard to Location polarity.
 
Breifly the class now has a get5PrimeEnd() method which gives you the most 5' point in the location (which is not necessarily the min). The 5' end is either specified at construction or determined from the order in which locations are joined in a union operation.
 
The toSymbols() method now correctly observes polarity and the toString() method gives a sensible representation of what the Location represents.
 
Please can people who are interested in things circular take this out for a spin before 1.3 rolls out.
 
- Mark
