Overlapping arrows in circular DNA

[ZongzhiWu]

Hi!
Can this tool be implemented to draw a circular DNA with all the gene arrows on the same circular ring and the arrows overlapping?

Implemented by revising the 122 line in CircularGraphicRecord.py (r = self.radius + level * self.feature_level_height) to r = self.radius + 0 * self.feature_level_height
