YAML Front Matter (YFM) parser for Markdown files

# YAML Front Matter (YFM) Parser
**yaml-front-matter** parses a valid YAML string into a `struct` which
implements the `DeserializeOwned` trait from serde.
Consider the following YAML content on the top of your markdown file:
```yml
---
title: 'Parsing a Markdown file metadata into a struct'
description: 'This tutorial walks you through the practice of parsing markdown files for metadata'
tags: ['markdown', 'rust', 'files', 'parsing', 'metadata']
similar_posts:
- 'Rendering markdown'
- 'Using Rust to render markdown'
date: '2021-09-13T03:48:00'
favorite_numbers:
- 3.14
- 1970
- 12345
---
```
This crate takes care of extracting this header from your markdown file and
parse extracted data using `serde` and `serde_yaml`.
## Example
```rust
use serde::Deserialize;
use yaml_front_matter::YamlFrontMatter;
const SIMPLE_MARKDOWN_YFM: &str = r#"
