unify spelling of Numpy/NumPy

The documentation is not consistent in spelling of “NumPy” (vs “Numpy”). For example, the reference manual uses both spelling in the introduction paragraph:

This reference manual details functions, modules, and objects included in Numpy, describing what they are and what they do. For learning how to use NumPy, see also :ref:user.

What is the official spelling? Make it consistent across all documentation.

This issue was initially reported at Scipy Lectures (https://github.com/scipy-lectures/scipy-lecture-notes/issues/250) by @btel and @emmanuelle.

Following the discussion on the mailing list and recommendations of @pdebuyl to close the issue:

• update the docs to use NumPy when we refer to the project and numpy only in relation to the module name
• explain the rules of “NumPy” spelling in the NumPy docs

I can help for this.

There are 61 files in numpy and 75 in doc.

$ cd numpy/
$ ack-grep -l Numpy | wc -l
61
$ cd ../doc/
$ ack-grep -l Numpy | wc -l
75

Should the release notes be modified? They could be considered “historical” data.

There are a few instances of “Numpy*” in the test code (the NumpyDoctest in nosetests), in the distutils code (NumpyDistribution class) and the NumpyVersion variable.

The C code seems to use “NumPy” consistently.

No problem for closing. The corresponding PR was merged.
