Version 1.10 3/13/2015

Added 3 New DRC Tests

VIA1 Pitch and Opening Size
Intended for via layers. Counts number of openings, computes the minimum pitch and the minimum opening size.

VIA2 Opening Size
Counts openings and reports on the number of non-truncated openings. Any opening with less than 50% of the average opening area is considered truncated.

Effective Capture Pad Size
Requires as input a parent layer (the layer containing the geometry that "captures" the pad) and a child layer (the layer containing the opening pad or captured pad.) Computes the "effective" size of the capture by analyzing the amount of material surrounding each pad to be captured.
