//Write a program that extracts from a given text all sentences containing given word.
//      Example: The word is "in". The text is:
//            We are living in a yellow submarine. We don't have anything else. Inside the submarine is very tight.
//            So we are drinking all the day. We will move out of it in 5 days.
//
//      The expected result is:
//              We are living in a yellow submarine.
//              We will move out of it in 5 days.
//
//      Consider that the sentences are separated by "." and the words – by non-letter symbols.
