Impact calculator POC

Library to calculate impact and impact uncertainty of a product system.

Concepts:

• Base product: Product that simply has an impact value and an uncertainty of this value.
• Compound product: Product made up from usage of other products (compound or base), with an uncertainty associated to the quantity of product used.

Limitations

• Cannot handle circular product systems (LCA tools needed for this).
• Does not handle unit conversion

TODO

• Implement different pedigree matrix coefficients (sector specific)
• Adapt basic uncertainty for geometric standard deviation calculation from pedigree matrix
• Add characterisation of the uncertainty related to the choice of the process (additional pedigree matrix for product usage)
• Implement Monte-Carlo loop
• Display contribution of each product to the total impact
• Add a way to make Monte-Carlo deterministic with seed
• Allow for variable correlation
• Add other types of uncertainty through new Amount classes
