		Registers a custom resource importer in the editor. Use the class to parse any file and import it as a new resource type.

	<description>
		EditorImportPlugins provide a way to extend the editor's resource import functionality. Use them to import resources from custom files or to provide alternatives to the editor's existing importers. Register your [EditorPlugin] with [method EditorPlugin.add_import_plugin].

		EditorImportPlugins work by associating with specific file extensions and a resource type. See [method get_recognized_extension] and [method get_resource_type]). They may optionally specify some import presets that affect the import process. EditorImportPlugins are responsible for creating the resources and saving them in the [code].import[/code] directory.


		Below is an example EditorImportPlugin that imports a [Mesh] from a file with the extension ".special" or ".spec":
		[codeblock]
		tool
		extends EditorImportPlugin

		func get_importer_name():
		    return "my.special.plugin"

		func get_visible_name():
		    return "Special Mesh Importer"

		func get_recognized_extensions():
		    return ["special", "spec"]

		func get_save_extension():
		    return "mesh"

		func get_resource_type():
		    return "Mesh"

		func get_preset_count():
		    return 1

		func get_preset_name(i):
		    return "Default"

		func get_import_optons(i):
		    return [{"name": "my_option", "default_value": false}]

		func load(src, dst, opts, r_platform_variants, r_gen_files):
		    var f = File.new()
		    if f.open(src, File.READ) != OK:
		        return FAILED

		    var mesh = Mesh.new()

		    var save = dst + "." + get_save_extension()
		    ResourceSaver.save(file, mesh)
		    return OK
		[/codeblock]
