User Agent Parser

Break a user agent string into the browser, operating system, device class and rendering engine it claims. Useful for log triage and fingerprinting. Treat the result as best effort, these strings are easily faked.

User agent strings are easily spoofed and this parse is heuristic. Use it as a signal, not as proof of what a client really is.
