Add tests for all docs examples Parametrize our docs example test to include all (now fixed) examples from the `READ.rst`. The examples themselves have been fixed/corrected to run but they haven't yet been updated in the actual docs. Once #99 lands these example scripts will be directly included in our documentation so there will be no possibility of presenting incorrect examples to our users! This technically fixes #108 even though the new example aren't going to be included directly in our docs until #99 lands.
