Library/Formula/open-zwave.rb

OpenZWave is a library for interacting with Z-Wave ("home automation") gateways. It builds a C++ shared library and headers, not an end-user binary.
Can a test be added to do something more substantial than e.g. `--version` or `--help`? See `cmake.rb` for an example of an application formula with a good test and `tinyxml2.rb` for an example of a library formula with a good test. Thanks!
