Work on AASList / AASListDetails / AASTreeview / SubmodelList

[seicke]

Description of Changes

1) no longer manually closable AASListDetails anymore

If aas-gui will be opening (without aas path parameter) the AASListDetails will be hide. The AAS List has its maximal height.

• Click on an AAS of the AASList opens the AASListDetails of the selected AAS; at the same time AASList will be downsized. AASList as well as AASListDetails will be shown.

• Further click on the same AAS closes the AASListDetails (= deselecting AAS); at the same time AASList will be enlarged back to its maximal height

---

2) Introduce new ENV variable SINGLE_AAS_REDIRECT

If variable is set as an URL

• the aas-gui will only show a single aas. The AASList will be hide, AASListDetails has its maximal heigth.

• the aas-gui hast to be opened with an aas path parameter, otherwise you will be redirected to the URL specified in the ENV variable SINGLE_AAS_REDIRECT

3) v-empty-state for no existing submodels in selected aas

Rules

PR#111 and PR#113 should be merged first.

Thank you for this very cool PR. I have some small suggestions:

• Separate in two env variables (activate feature, redirect URL)
• When feature is active and redirect URL invalid/not set a new 404 Page should be shown
