[SpecFlow] Add Cucumber Expressions

Cucumber Expressions are a new, simpler way to glue Gherkin steps to step definition methods. They are currently supported in Cucumber, Cucumber-JS, and Cucumber-JVM. It would be fitting to support them in SpecFlow as well.

Design considerations:

• The syntax of Cucumber Expressions in SpecFlow should be compliant with the other Cucumber projects.
• Programmers should be able to easily choose between step definition styles for Cucumber expressions, regular expressions, and method naming conventions. (This could be done with new attribute names, options, or smart string matching.)
• Built-in parameter types for int, float, word, and string should be supported.
• Programmers should also be able to define custom parameter types.
• Optional text, alternative text, and escaping should be supported.

  I really like the Cucumber Expressions instead of the Regular Expressions (I mean addtional). It's more expressiv and easier to understand for many test automation developers.
  
  Is there a plan to add this feature and when is it planed? Do you recommend using CucumberExpressions.SpecFlow instead?

  Thanks, Roland

  As you noticed Gaspar Nagy created a plugin to use Cucumber Expressions now with SpecFlow (https://github.com/gasparnagy/CucumberExpressions.SpecFlow). There is no problem with using it.

  Additionally, he is currently working on integrating it into SpecFlow itself.
