Expressions

Many node properties can be set with "expressions", allowing inserting event properties into text. Consider the following node properties:

The pieces of text surrounded by curly braces are called "interpolations". In this case, the interpolations take the twitch bits and twitch name event properties from the Twitch On cheer node and insert them into the text to be written to a file.

In the future, expressions will be able to do more than just insert properties - including list processing, changing case, switching between different messages, etc.
