New feature - match sentence

[tetele]

Consider the following sentence: turn off the lights and close the blinds.

This sentence could be matched with {sentence1} and {sentence2} where both sentences are defined as wildcards, but if either sentence contains an and, the actual split may not work properly. More over, there's not guarantee that either sentence defined as a wildcard will be interpretable as a sentence in the end.

It would be useful to have a special kind of list that only matches sentences, such as:

lists:
  sentence1:
    sentence: true
  sentence2:
    sentence: true

intents:
  And:
    data:
      - sentences:
          - "{sentence1} and[ then] {sentence2}"
