"*.GLOBAL" as equivalent to ".GLOBAL". Corrected the property
matching to handle property combination when no "critical"
property is given. Critical properties exist when one property
must remain constant and equal for other properties to combine,
such as transistor length. But, for example, capacitors can
combine area without any restriction based on another property.
Also, corrected the property matching code to allow more than
one property to be additive (example: capacitor area and
perimeter). Corrected the equation for adding properties in
parallel combination.
