To be able to use spectacle as a tool for static tag analysis for gauge, I need to be able to execute the same tag expressions in spectacle as is possible in gauge.
In gauge, it is possible to have tag expressions with round brackets - this is not yet possible in spectacle.
Give spectacle the ability to work with tag expressions containing (possibly more than one set of) round brackets like in "(tagA | tagB) & !tagC".
Right now using () in spectacle gives: "No Specifications found that matches the given tag expression..."
