Major release (1.0.0)

[bobmyhill]

As a companion to the new paper, we should make another major release. In this release, we should add the following:

• Add composition fitting functions (Solution and bulk composition fitting #382)
• Add polytope stuff (Polytope #406)
• Add equilibration functionality (Equilibrate #407)
• Add HP98 EOS (H+P melt endmembers #410)
• Add HP2011, HGP2018 melt phases (based on the HP98 EOS, H+P melt endmembers #410)
• Add ternary terms to the subregular solution model (Subregular ternary #409)
• Add existing examples (updated examples and documentation #411)
• Add detail to the examples in the manual (updated examples and documentation #411)
• Mention/describe the contributions and ipython directories (mention contrib directory #412)
• Bug fix (fix modified properties with pvt eos #413)
• Add isentropic to appropriate methods in AnisotropicMaterial (add isentropic qualifier to AnisotropicMaterial #419)
• Double check that the autogenerated documentation for the code base is complete (updated examples, made cvxpy and cdd optional #421)
• Restructure the code (BurnMan 1.0 restructuring and documentation #422)
• Check manual compiles successfully on ReadTheDocs.

Final steps once we have the code ready:

• Open zenodo, start new version, reserve DOI (currently at the top of Basic Information)
• New branch (burnman-Major.Minor)
• Bump version number in new branch (in burnman/version.py)
• Update changelog.txt with major changes since the last release.
• Update setup.py (if necessary, probably only Python versions need checking, but might be worth checking that sudo python setup.py sdist bdist_wheel works without errors)
• Update new link to the zenodo version (using the new reserved DOI) in burnman/init.py
• Update new link to the zenodo version (using the new reserved DOI) in docs/index.rst
• Update new badge link to zenodo (using the new reserved DOI) in Readme.md
• Push new branch to Github upstream burnman-Major.Minor (not master)
• Make release on Github using upstream burnman-Major.Minor branch
• Make release commit (tag, not branch) active on readthedocs (you'll need to build from master first so that ReadTheDocs finds the new release tag)
• Build documentation on readthedocs
• Download zip file
• Upload new zip file to zenodo, fill in details on website (including new link to ReadTheDocs)
• Save and publish in zenodo
• Update GitHub release with new zip files and link to the ReadTheDocs documentation
• Push release to Pypi (from clean directory):

1. sudo python setup.py sdist bdist_wheel (sudo unfortunately required)
2. twine check dist/* (to check zip and wheel)
3. twine upload --repository-url https://test.pypi.org/legacy/ dist/* (to test upload, can get password from the pypi website)
4. twine upload dist/* (the final upload to Pypi)

• Merge upstream burnman-Major.Minor branch to master
• Bump version numbers in version.py on upstream master
• version=[Major].[Minor+1].0pre
• short_version=[Major].[Minor+1].0
• Check and update homepage (especially the downloads section and the zenodo links)
