[Dev] New package

[ocots]

@frapac @jbcaillau @PierreMartinon

What do you think we need to do before trying to register OptimalControlProblems.jl into the General Julia registry?

[jbcaillau]

@ocots go!

NB. @0Yassine0 would be nice to use the new syntax ocp = @def ... (instead of @def ocp ...)

[ocots]

@JuliaRegistrator register

[JuliaRegistrator]

Registration pull request created: JuliaRegistries/General/115146

Tip: Release Notes

Did you know you can add release notes too? Just add markdown formatted text underneath the comment after the text
"Release notes:" and it will be added to the registry PR, and if TagBot is installed it will also be added to the
release that TagBot creates. i.e.

@JuliaRegistrator register

Release notes:

## Breaking changes

- blah

To add them here just re-invoke and the PR will be updated.

Tagging

After the above pull request is merged, it is recommended that a tag is created on this repository for the registered package version.

This will be done automatically if the Julia TagBot GitHub Action is installed, or can be done manually through the github interface, or via:

git tag -a v0.1.1 -m "<description of version>" e28285cb58c3a56e70584679b8468bf40125509f
git push origin v0.1.1

Also, note the warning: This looks like a new registration that registers version 0.1.1.
Ideally, you should register an initial release with 0.0.1, 0.1.0 or 1.0.0 version numbers
This can be safely ignored. However, if you want to fix this you can do so. Call register() again after making the fix. This will update the Pull request.
