Issue log

2010-11-23 12:38	Mathew Topper <mathew.topper@...>	closed with disposition fixed
Added protection for duplicates into TwoD_Wave_Form.linear_cross and also a test for the given point being right on the crossing point.

2010-11-23 12:04	Mathew Topper <mathew.topper@...>	commented
I think that TwoD_Wave_Form.linear_cross is too simple. It just picks up the next node and assumes that the crossing lies there. It doesn't check for dupes. I don't think it handles the zero case either. Need to make it smarter. Might consider sanitising the input for dupes as well, but building the protection in now, might be safer.
