Knit & Render Markdown in Text areas

Why is it useful:

- Markdowns represent reproducible research where a user has to document all the steps taken to reach that point in the analysis. It is widely used to replace "by hand" steps like downloading the data & transforming before getting it into Spotfire.

- Such a functionality complements the data panel source view: with the goal of giving the end user greater understanding into the data transformation process. Markdown scripts with documentation about data source & transforms (download.file unzip etc) provide the user with data provenance amongst other obvious benefits of documentation.

- Why specifically markdowns instead of using text areas? Because of ecosystems. RStudio & GitHub etc. can seamlessly pick up & understand a markdown. Unlike text area instructions that user would have to implement by hand.

Who does it benefit:

Spotfire Developer persona which branches into software engineers, Statisticians, Data Scientists etc.

The basic implementation should be able to render an HTML correctly (sample HTML) which should be rendered similar to .MD file but instead has omission & code syntax issues.

In the long run ideal scenario would be to start with raw .RMD file in text area & be able to render it to generate HTML & .MD
