	Script: Documentation Generation
	Purpose: To generate output based on a driving view

	Author: Richard Heward - Tame Blue Lion Ltd

	This generates a markdown file with the embedded images and text based upon a driving view in Archi of groups that trigger each other and embedded views.
	See my blog for a more detailed explaination. https://www.tamebluelion.co.uk/blog/archi-documentation

	Setting embed to false will have the images saved to file and references placed in the document. It's then up to your markdown engine. This isn't that well tested.
	Setting
	Note - markdown can be converted to PDF / Word Docs or anything. I've used pandoc command line to do this.

    Created: 8-Oct-2019
    11-Oct-2019 - Included sketch views in the driving view.
    27-Nov-2019 - Added improved object layout as tables, plus their properties
    29-Nov-2019 - Now includes all view objects via a .find instead of a .children.
	12-Dec-2019 - Sorts the properties so they are grouped by element type
	24-Jan-2020 - Allowed inclusion settings to be set by group. Inherited by nested groups. Made catalogue columns more dynamic (configurable in future?). Refactored recursive functions. (Jared Pritchard)
    28-Jan-2020 - Outputs the linked views in the visual left-right top-bottom order they are drawn in a driving group. This was tricky and probably messy code, but it works.
    29-Jan-2020 - includes a hardNewpage variable to drop the text NEWPAGE into the output if your target is MS Word. This allows for post processing find-replace to swap it for proper new pages. It does this for all header levels in the listofNewpageheaders variable.

	Script: Documentation Generation
	Purpose: To generate output based on a driving view

	Author: Richard Heward - Tame Blue Lion Ltd

	This generates a markdown file with the embedded images and text based upon a driving view in Archi of groups that trigger each other and embedded views.
	See my blog for a more detailed explaination. https://www.tamebluelion.co.uk/blog/archi-documentation

	Setting embed to false will have the images saved to file and references placed in the document. It's then up to your markdown engine. This isn't that well tested.
	Setting
	Note - markdown can be converted to PDF / Word Docs or anything. I've used pandoc command line to do this.

	Created: 8-Oct-2019
	11-Oct-2019 - Included sketch views in the driving view.
	27-Nov-2019 - Added improved object layout as tables, plus their properties
	29-Nov-2019 - Now includes all view objects via a .find instead of a .children.
	12-Dec-2019 - Sorts the properties so they are grouped by element type
	24-Jan-2020 - Allowed inclusion settings to be set by group. Inherited by nested groups. Made catalogue columns more dynamic (configurable in future?). Refactored recursive functions. (Jared Pritchard)
	28-Jan-2020 - Outputs the linked views in the visual left-right top-bottom order they are drawn in a driving group. This was tricky and probably messy code, but it works.
	29-Jan-2020 - includes a hardNewpage variable to drop the text NEWPAGE into the output if your target is MS Word. This allows for post processing find-replace to swap it for proper new pages. It does this for all header levels in the listofNewpageheaders variable.
