TransformationExecutionStep

interface TransformationExecutionStep<T, R, E : Expect<R>>

Defines the minimal contract for the execution step of a subject transformation process - i.e. the step after choosing all options.

collect	`abstract fun collect(assertionCreator: Expect<R>.() -> Unit): Assertion` Finishes the transformation process by collecting the assertions the given assertionCreator creates for the subject of type R resulting from the transformation and returns the assertions as a single Assertion.
collectAndAppend	`abstract fun collectAndAppend(assertionCreator: Expect<R>.() -> Unit): Expect<T>` Finishes the transformation process by appending the Assertion which is returned when calling collect with the given assertionCreator.
transform	`abstract fun transform(): E` Finishes the transformation process by simply performing the transformation as such.
transformAndAppend	`abstract fun transformAndAppend(assertionCreator: Expect<R>.() -> Unit): Expect<R>` Finishes the transformation process by carrying the transformation out and appending the assertions the given assertionCreator creates for the subject of type R resulting from the transformation as single assertion.

fun <T, R> TransformationExecutionStep<T, R, *>.collectAndLogicAppend(assertionCreator: AssertionContainer<R>.() -> Assertion): Expect<T>

Finishes the transformation process by appending the Assertion which is returned when calling TransformationExecutionStep.collectAndAppend with _logicAppend and the given assertionCreator.

BaseTransformationExecutionStep	`abstract class BaseTransformationExecutionStep<T, R, E : Expect<R>> : TransformationExecutionStep<T, R, E>` Step which has all necessary information to perform a subject transformation (subject change/feature extraction etc.) and now allows to decide how it should be done, especially regarding potential sub-assertions which should be applied to the new resulting subject.
ExecutionStep	`interface ExecutionStep<T, R> : TransformationExecutionStep<T, R, FeatureExpect<T, R>>` Step which allows to decide how the transformation shall be executed.
ExecutionStep	`interface ExecutionStep<T, R> : TransformationExecutionStep<T, R, Expect<R>>` Step which allows to decide how the transformation shall be executed.
