Remove date from jupyter exported pdf

Remove date from jupyter exported pdf

Add \date{} to share/jupyter/nbconvert/templates/latex/base.text.j2 anywhere before /maketitle (e.g. before the title block)

If you want to control it using the notebook metadata, add this instead:

    ((* if nb.metadata.get('nodate', false) *))
    \date{}
    ((* endif *))
