all of this stuff is super rough and not well thought out yet. all of this stuff is super rough and not well thought out yet. i'm just checking in so we have some stuff to work with for the sprint tonight.

79 Persistence
80 node instance saves:
81 node name, id, and such
82 input ports:
83 any port details
84 what the port connects to
85 values:
86 maybe UI.Scale level
87 maybe group contents

102 Ports
103 Port: "scalar"
104 MultiPort: "array of Port"
105 ^ all wrong
106
107 Ports II:
108 min/max number of connections
109 (failure to fit these numbers means port is "deactivated")
110 "Normal" ports are min=1, max=1
111 "Multiports" are min=0, max=None
112 "Binary" ports are min=2, max=2
113 oh yeah, there are two totally different types of ports
114
115 Input ports: min/max numbers of connections
116 store current connections
117 Output ports: nothing
118 store nothing!
