convert to package, update error codes

[jacobwhall]

Hi there,

I forked this repo yesterday and made some changes I'd like to contribute.

First I merged in @ShevFA's work packaging this repository, and then made some additional tweaks to make using the package more intuitive for me. Here's a summary of what I did:

• added some code to usgs_m2m/__init__.py to make imports look something like from usgs_m2m import API as M2M
• put UsageExample.py into an examples directory and edited it to work with the package
• combined a couple of errors to match the error code documentation, and tested that they work as expected
• found an undocumented error code (INPUT_PARAMETER_REQUIRED) and added it to the error handling logic

This can be installed with pip install https://github.com/jacobwhall/usgs-machine-to-machine-API/archive/master.zip (see here). You can also checkout the branch and run pip install -e . to install it in editable mode.

If you decide to merge this, I recommend editing pyproject.toml to update your contact info and any other metadata you'd like. I could help setup a PyPI publishing workflow should you be interested.

Cheers, Jacob

Thank you for contributing to the development of this repository.

I am self-taught and my modest programming skills leave much to be desired.

If you have a desire to develop this wrapper - I will gladly accept your contribution.

You wrote a bit of code that I found very useful. Thank you for making the world a better place.
