TA-browscap_express - HTTP User Agent lookup with browscap

This technology add-on provides a dynamic lookup to add fields to user agent (browser) data. It is a re-write of the TA-browscap add-on by David Shpritz. The data is provided by the Browser Capabilities Project. The parser is a re-write of the parser in the pybrowscap library. This add-on is faster than other browscap based projects, because it maintains a cache of previously matched user agent strings. This significantly improves the time for subsequent lookups, without sacrificing accuracy.
