Document merge function import

[IlyaSemenov]

Here https://github.com/mozilla-neutrino/webpack-chain#config-module-rules-uses-loaders-modifying-options the example says:

config.module
  .rule('compile')
    .use('babel')
      .tap(options => merge(options, { plugins: ['babel-plugin-syntax-object-rest-spread'] }));

However it's not mentioned anywhere where merge is supposed to come from. I believe that should be documented at least once.

I hope this should be documented. I imported merge like const merge = require('deepmerge').

@eliperelman is this example referring to deepmerge's merge() or that from babel-merge? I'm presuming the latter?

[eliperelman]

I left it as generic at the time so users could implement how they saw fit, but using babel-merge is probably the best way.

I had success with webpack-merge:

var merge = require('webpack-merge');
