How imperialchepi/healthgps works

Health-GPS is a C++ microsimulation for evaluating health and economic effects of policy scenarios. A user supplies configuration and project data; the console host parses and validates inputs, assembles model input, runs baseline or intervention trials, and writes result files. The documented simulation stages cover demographics, socioeconomic factors, risk factors, and disease outcomes. The tree and excerpts support the host, input, repository, and output layers; several domain connections are documented in the README rather than visible in sampled implementations.
