Aspect line style
This is type of line that will be drawn between 2 planets that are in aspect. The default is a solid line, but you can choose some variations here. I had in mind the idea that aspect lines would be solid whereas testimony lines would be some variation of a dotted line. When the AspectStyle property is asHellenistic, the program asserts a difference in the calculation between testimony and aspect and the two line styles will be different. With this set to asPlatic or asShowAll, then only the AspectLineStyle is used anyway.
