Minor fixes (#613)
* Minor doc syntax fix
The numpy documentation had a bad :file: reference (was using double
backticks instead of single backticks).
* Changed long-outdated "example" -> "tests" wording
The ConstructorStats internal docs still had "from example import", and
the main testing cpp file still used "example" in the module
description.

When it is invoked with a different type (e.g. an integer or a list of

Data in NumPy arrays is not guaranteed to packed in a dense manner;
furthermore, entries can be separated by arbitrary column and row strides.
