/**
* Creates a PostCSS plugin with a standard API.
*
* The newly-wrapped function will provide both the name and PostCSS
* version of the plugin.
*
* ```js
* const processor = postcss([replace])
* processor.plugins[0].postcssPlugin //=> 'postcss-replace'
* processor.plugins[0].postcssVersion //=> '6.0.0'
* ```
*
* The plugin function receives 2 arguments: {@link Root}
* and {@link Result} instance. The function should mutate the provided
* `Root` node. Alternatively, you can create a new `Root` node
* and override the `result.root` property.
*
* ```js
* const cleaner = postcss.plugin('postcss-cleaner', () => {
* return (root, result) => {
* result.root = postcss.root()
* }
* })
* ```
*
* As a convenience, plugins also expose a `process` method so that you can use
* them as standalone tools.
*
* ```js
* cleaner.process(css, processOpts, pluginOpts)
* // This is equivalent to:
* postcss([ cleaner(pluginOpts) ]).process(css, processOpts)
* ```
*
* Asynchronous plugins should return a `Promise` instance.
*
* ```js
* postcss.plugin('postcss-import', () => {
* return (root, result) => {
* return new Promise( (resolve, reject) => {
* fs.readFile('base.css', (base) => {
* root.prepend(base)
* resolve()
* })
* })
* }
* })
* ```
*
* Add warnings using the {@link Node#warn} method.
* Send data to other plugins using the {@link Result#messages} array.
*
* ```js
* postcss.plugin('postcss-caniuse-test', () => {
* return (root, result) => {
* root.walkDecls(decl => {
* if (!caniuse.support(decl.prop)) {
* decl.warn(result, 'Some browsers do not support ' + decl.prop)
* }
* })
* }
* })
* ```
*
* @param {string} name PostCSS plugin name. Same as in `name`
* property in `package.json`. It will be saved
* in `plugin.postcssPlugin` property.
* @param {function} initializer Will receive plugin options
* and should return {@link pluginFunction}
*
* @return {Plugin} PostCSS plugin.
