ConvertFrom-Markdown is used for converting a markdown document or string to a MarkdownInfo object.
It can optionally return a HTML or VT100 encoded string in addition to a AST of the markdown document.
Show-Markdown is used to either display the VT100 encoded string on console or redirect the HTML string to the browser.
Set/Get-MarkdownOption cmdlets get be used to view or set markdown rendering options.
