Base class for any views plugin types.

Via the @Plugin definition the plugin may specify a theme function or template to be used for the plugin. It also can auto-register the theme implementation for that file or function.

theme: the theme implementation to use in the plugin. This may be the name of the function (without theme_ prefix) or the template file (without template engine extension). If a template file should be used, the file has to be placed in the module's templates folder. Example: theme = "mymodule_row" of module "mymodule" will implement mymodule-row.html.twig in the [..]/modules/mymodule/templates folder.
register_theme: (optional) When set to TRUE (default) the theme is registered automatically. When set to FALSE the plugin reuses an existing theme implementation, defined by another module or views plugin.
theme_file: (optional) the location of an include file that may hold the theme or preprocess function. The location has to be relative to module's root directory.
module: machine name of the module. It must be present for any plugin that wants to register a theme.
