What is required for the release?

[lionelkusch]

After each release for the moment, the branch will be created, and a tag on the last commit of the release will be added (see issue #53).

Regarding a release:

• Do we do additional tests and benchmarks? or Do we just stay with integration tests and small benchmarks only?
• Do we provide an update on more important or complex examples?

[bthirion]

For the moment, we stay with standard tests and small benchmarks.
Let's start with simple examples and then we'll consider if more complex examples are needed. But I don't want to make things too complex nor too heavy.
