Write Gherkin syntax into DSL like methods

[corrado4eyes]

Gherking syntax can be written as DSL syntax since it contains a "Sentence" that can include some parameters and it wraps a method that represent the action of that given sentence.

Here are the method that should be included in the wrapper

• Gherkin syntax Given #26
• Gherkin syntax When #27
• Gherkin syntax Then #28
• Gherkin syntax And and But #29
• Feature (Optional for now)
• Scenario (Optional for now)
