 This projects presents a prototype of our algorithm that boosts comparison-based retroactive feature tracing. 
 The used retroactive tracing method is heavily inspired by ECCO.

 2. Iterate over the collection of variants for which traces are to be computed, creating a `ProductPassport` for each and adding it to the list.
 3. Instantiate the TraceBoosting algorithm with the product passports, working directory, and the supported language for tracing.
 4. Retrieve the list of products from the TraceBoosting instance.

+5. Apply the proactively collected traces to the products by settings the mappings for the products' AST nodes.
 6. Compute the Main tree, which represents the merged variant AST with feature traces.
 
 Here is a code snippet demonstrating how to use the TraceBoosting algorithm:
