Extended Markdown Iterator

This crate wraps the event iterator created by equt_md to provide a more general while powerful interface.

Difference between those crates

• equt_md parses the markdown into event iterator.
• equt_md_frontmatter parse the markdown frontmatter into Rust data structure.
• equt_md_error contains all errors in these crates.
• equt_md_ext wraps and extends the crates above for easy using.
• equt_md_html renders the iterator into HTML.
