Cucumber Tag Expressions is a simple query language for tags. The
simplest tag expression is simply a single tag, for example:

@smoke

A slightly more elaborate expression may combine tags, for example:

@smoke and not @ui

Tag Expressions are used for two purposes:

- Run a subset of scenarios (using the --tags expression option of
  the command line)
- Specify that a hook should only run for a subset
  of scenarios (using conditional hooks)
