Runtime port representation

[emil14]

It's not clear what data must be present at runtime level due to issues with maps and structs. Current implementation assumes names and indexes but it may be wrong

TODO figure out real cases that must be solved

[emil14]

TODO think better

// compiler 
type Ports map[string]Port

type Port struct {
  Type PortType // single | array
  Len uint8 // always 0 for single
}

// runtime

type Ports map[string]map[PortAddr]chan Msg // node_full_path -> ...

type Connections []Connection
type Connection struct {
  From PortRef
  To []PortRef
}

type PortAddr struct {
  IsArrEl bool
  Idx uint8
  Name string
}

type PortRef struct {
  IsArrEl bool
  Idx uint8
  Name string
}

// core
type Ports map[string]Port

type Port struct {
  Type PortType // single | array
  Single chan Msg
  Arr []chan Msg
}

why this exists?
