Noticed these when comparing pdf outputs from subsequent runs of building the docs. Mostly put here so they don't get lost.

• some functions have function objects as default values which are leaking memory addresses into the docs. These should probably be replaced by None and assigned the default value inside the function.
• the author list in the pdf docs needs a line break
• There are some examples that use un-seeded random number
• inheritance diagrams are missing (but that might just be the environment I am building in)
