[Moose-dev] Roassal ROShorterDistanceAttachPoint: refactoring and possible enhancement

Hi all, I saw two instances of code duplication in ROShorterDistanceAttachPoint so I refactored the class, changed some method names to make their purpose cleaner and added some comments. @Alexandre: If you like the changes, could you integrate them into Roassal? The filed out class can be found here: http://cl.ly/code/392s3y1V2A0N In a next step I added an offset parameter which can be used to offset the attach point positively or negatively on one of the four possible attach 'sides'. The purpose of the offset can be seen in the following screenshot: http://cl.ly/image/0d343Z1L0b00 It allows for example to have multiple edges from and to the same element (with different offsets). I'm note sure whether you would want the offset-possibility in ROShorterDistanceAttachPoint or if I should create a subclass for it. If you'd like to integrate it directly, the filed out class with the offset parameter can be found here: http://cl.ly/code/1T3c310J2r06 If not I will create a subclass. Cheers, Dennis
