(what happen i import the same note again?) You can re-importe the same note many times, the note id is re-generated each time and is different for each import. But the **paragraphId** remains the same. Remark: in the patch I mentioned above, I change the source code to re-use the paragraphId on note import BUT the jobId (the `Paragraph` class extends the `Job` class) is regenerated each time to avoid unicity issue for jobId when we re-import twice the same note ... So in the last update of this PR, `z.angularBind('label', 'value', 'paragraphId')` only bind an Angular variable to an unique paragraph and the current interpreter used by this paragraph
