This tag provides an archived version of v3 of the model. It has been used for initial TPP work and included significant improvements in the way the model is built. Compared to v2.5, the model was split into multiple source files to ease modifications (thanks to Diggory Hardy's work) and interventions were implemented more throughly.
Refactored version of the model, based from the legacy branch with a lot of new implementations regarding intervention and parameters. It's not labeled v2.0 because a lot of slight bugfixes and modifications were done in-between legacy and the current version.
