Simple jekyll pre_render hook to add ordered number to headings.

By default, the plugin will attempt to modify pages, posts, and documents. To specify custom jekyll file types, modify your site's _config.yml

# _config.yml

numbered_headings:
  hooks:
    - guides
    - specs
    - my_custom_docs

It's tested only on jekyll 3.3.1.

Add this line to your application's Gemfile:

gem 'jekyll-numbered-headings'

And then execute:

$ bundle

Or install it yourself as:

$ gem install jekyll-numbered-headings

Then, add to your _config.yml:

gems:
  - jekyll-numbered-headings

You can use following syntax on your pages, posts, and collections.

##1. At first

###1. One thing

###1. Another thing

##1. Second

##1. Third

will be replaced to:

## 1. At first

### 1.1. One thing

### 1.2. Another thing

## 2. Second

## 3. Third

That's it!
