+    Main class of the doc_ai_convert extension
+
+    This extension performs the following two actions:
+    1) Recognize intended dimensions of original document.
+        - If the AI document was set up with a size given in picas, cm, mm, or in,
+          and then exported to SVG, no conversion is needed.
+        - If the AI document was set up with any other dimensions,
+          (point, yard, px, ft/in, ft, or m), then the exported SVG
+          will be in units of 72 DPI pixels. This causes an issue,
+          as Inkscape uses CSS pixels (px) which are at 96 DPI.
+          In this case, we re-interpret the size as 72 DPI points (pt),
+          which will convert the artwork to appear at the correct size.
+    2) Recognize Adobe Illustrator layers.
+        - Group (<g>) elements with non-empty data-name attributes are
+          groups in an Illustrator SVG document.
+        - We re-label these as layers such that Inkscape will recognize them.
