Inconsistent example namespaces

[QuazChick]

Issue

For most code examples, the wiki namespace is used in identifiers, however some examples have random namespaces like foo or example.

Note: the feature types page contains many example namespaces which represent different types of example add-on. It may be best to leave these unchanged.
