Matcher Architecture

claircore/internal/matcher
claircore/libvuln/driver

The Matcher architecture is based on a data flow application.
The Matcher functionality is implemented via a Controller in the matcher package and interface definitions within the libvuln.driver package.
When libvuln is provided a IndexReport the Matcher package will transform the IndexReport into a stream of IndexRecord structs.
The Matcher package then instantiates each implemented driver.Matcher interface and utilizes these implementations to determine if particular IndexRecord structs are vulnerable.
