Variables
Variables encode conditions for a node, when the dialogue flow reaches that node, the contents of that node only executes if the conditions are met. Values can be assigned to variables prior to entering a node although those variable assignments only take effect if the entering conditions are met. Values can also be assigned to variables when leaving the node, in the leave node settings.
