Descriptions and tutorials

[lateef-k]

I've realized that most of the tools and configs make sense because we're familiar with them but they're actually pretty cryptic. It's not quite clear what the turtle module does for example, or what the config fields mean. The module names are don't help much too, for example what does Mod fill mean? Obviously the names can only be so descriptive, we should use the description property in the module object:

const MODULE_Empty = {
	viz: Empty_VIZ,
	name: "",
	description: "",
	configSchema: Empty_SCHEMA
}

And show it in the panel belonging to that module. It should include information about what it does, what it expects the config fields to be, and restrictions on types of sequences if there are any. Alternatively the description can be short and provide a link or a button that leads to an entry in the user manual page which exists but is unused right now. The manual needs at least a tutorial on using the website in general.
