Brendan's Flavor of Markdown: I'll build my own markdown format, what could go wrong?

# Brendan's Flavor of Markdown

## About 
I had decided to do a markdown converter as a small summer project in order to gain more experience with rust.  
It has taken far longer than I thought it would, in part due to excessive (for Ireland) heat but mostly due to the rabbit-hole that Markdown ended up being.

The end result is I ended up creating my own flavor of markdown.  
It is both stricter than Commonmark, yet at the same time more permissive.  

Stricter: 
* ``__`` is no longer used for ``<strong>``, only ``**`` is.
* Lazy continuation is disallowed.
* Inline spans now have double identifiers.
  * ``<`` and ``>`` to ``<<`` and ``>>``
  * The same happens with code spans. 
  
Permissive:
* Extensions:
  * Tables.
  * Spoilers.
  * Strikethrough.
* Leading whitespace no longer triggers a code block, so it is now possible to properly align headers.


I honestly don't expect anyone besides myself to use it.  
The existing flavors have been well established, and I dont have the clout of Gitlab/Github/Bitbucket/Reddit to get folks to use it.  
Not only that, this converter is currently a mess I have to split up for readability.  
I am also pretty sure that there are some nuanced bugs in it however I am pretty sure the idea behind the changes is sound.

As a summer project thought it is mostly successful, I have gained a decent bit more proficiency with rust.  
The conversion has no external dependencies (serde and toml are to read the optional config files).  
It also is the first crate I have pushed to crates.io.
