New features

Dear Flexi Team:
Please consider pulling our document describing several new tutorial problems that we developed for Flexi. Please contact me at any time if you have comments or questions.

Hi, many thanks for using and especially contributing to FLEXI!
We will have a look at you new testcases and come back to you if we have any questions (which we will probably have)!

Hi, thank you for developing flexi, we have been able to get some very nice shock implosion results with it. We would like to contribute these for others, along with some code mods that allowed us to run them. How would be the best approach to do this? They are not really tutorials, they are more extended problems that may not have general interest. Would it be better to add these to the flexi-extensions repo instead of the tutorials? Please see this interesting implosion movie below:

Thank you for your contribution. While we like the results and documentation, we feel like size of the files is too large. Every user would need to wait for the complete download during cloning and we thus feel reluctant to merge the branch into our master.

At the same time, we would like your contribution to be easily accessible. We do not feel that documentation relevant to the main branch should be stored in the flexi-extension repository. We are currently in the process of internal re-organization on how we make such information publicly accessible in form of a flexi-testcase submodule. However, the process is still ongoing and we thus ask for your patience.

I will leave the PR open, so any new development can be reported here.

Very good, we definitely understand the large file issue. I will reformulate this commit as hopr is used to generate the initial h5 files, if we leave those out it is a simple matter to use hopr to generate what is needed. I'll also rebase this fork to be off the tip of the current master branch. Thank you very much!
