+Ports
+ Port: "scalar"
+ MultiPort: "array of Port"
+ ^ all wrong
+
+ Ports II:
+ min/max number of connections
+ (failure to fit these numbers means port is "deactivated")
+ "Normal" ports are min=1, max=1
+ "Multiports" are min=0, max=None
+ "Binary" ports are min=2, max=2
+ oh yeah, there are two totally different types of ports
+
+ Input ports: min/max numbers of connections
+ store current connections
+ Output ports: nothing
+ store nothing!
