+TODO for Graphalyze
+===================
+
+* Report framework
+    * Extend the report framework
+    * Explore options for generating multiple files
+    * Differentiate between "large" and "small" images
+    * The pandoc code (especially elements) is a bit of a mess... can it be cleaned up?
+
+* Analysis stuff
+    * Default graph -> alg -> report element stuff
+
+* Write a README
