Inline MD codeblock with double backticks

A pair of single backticks signify an inline code block in Markdown. But if you need to put a backtick in that code block the backtick ends the codeblock!

Another way to signify an inline codeblock is with double backticks, two backticks in sequence on either side of the codeblock.

When using double backticks for a codeblock, a single backtick within the codeblock will be interpreted as just that, not the end of the codeblock.
