Add example with parameterized Scenario Outline

When using a Scenario Outline it is possible to use a placeholder in the
name of that Scenario Outline. The resulting pickle will have the
placeholder replaced with a value from the example tables.

This allows us to test use cases where this matter such as:
- cucumber/junit-xml-formatter#34
- cucumber/testng-xml-formatter#4

Fixes: #96

-  different data each time - this can be done by placing an Examples table underneath
-  a Scenario, and use <placeholders> in the Scenario which match the table headers.
