--[[ Transmisson.lua
This file contains all transmission related functionality, e.g. import/export and chat links.
For that it hooks into the chat frame and addon message channels.

Noteable functions in this file are:

DisplayToString(id, forChat)
Converts the display id to a plain text string

DataToString(id)
Converts the display id to a formatted table

SerializeTable(data)
Converts the table data to a formatted table

Import(str, [target])
Imports an aura from a table, which may or may not be encoded as a B64 string.
If target is installed data, or is a uid which points to installed data, then the import will be an update to that aura
