Added the `autoFallback` optional parameter to `GetMaterialsByModel`.
This flag controls whether the search automatically descends to
subcategories when no matches are found in the target category.
- Defaults to True to maintain previous recursive behavior.
- When False, the search is restricted strictly to the specified category.
- Updated documentation with usage examples and logic explanations.
Refactored the material retrieval logic in GetMaterialsByModel to
automatically search within subcategories if no matches are found in the
specified parent category.
- Added FilterCategoryWithSubcategories helper function to handle recursive
searching and fallback logic.
- Restructured main function to delegate filtering to the new helper.
- Enhanced code comments to clarify the step-by-step matching process.
Refine project overview to include specific business context (Blaidy Company) and the main workbook file. Restructure the architecture section into a layered object-oriented design (Data, Processing, Application layers) and define the responsibilities of core VBA classes.
Add new technical documentation sections covering:
- Model number format parsing structure
- Condition expression language syntax
- Category hierarchy logic and picking strategies
- Material matching pipeline flow
Include VBA code examples for key methods such as CollectAllMaterials and GetMaterialsByCategoryAndModel to illustrate recursive traversal and material retrieval logic. Clarify the structure of key Excel configuration sheets.
