VsdxParser

Parse a vsdx file.

Retrieve the contents of pages from a .vsdx file and insert them into documents, one document per page.

Get the content of the pages of a vsdx file.

Get the relationships of a page and the relationships of its relationships, etc... recursively. Pages are based on other pages (ex: background page), so we need to get all the relationships to get all the content of a single page.
