draft for heterogeneous catalysis app

• restructure results part: subsections for products and reactants
• make products and reactants quantities searchable in explore app
• add quantities in histogramms that cannot yet be added in scatterplots
• select proper filter for catalysis app (at the moment surface area,-> is not the best)
• recheck normalize function in python schemas -> needs update for NH3 decomp, later; moved to plugin
• test example data sets:
• oxidation,
• ~~ NH3 decomposition and ~~ -> later
• CO hydrogenation
