Problem:
In text-editing and word-processing applications, one formatting conversion sometimes
used to indicate that a piece of text is a footnote or an endnote is to mark it with some
special delimiters such as { and }. When the text is formatted for output, these notes are
not printed as a normal text but are stored in a queue for later output. Write a program
that reads a document containing endnotes indicated in this manner, collect them in a
queue and print them at the end of the document.
Here are the file samples:

Stopping By Woods on a Snowy Evening
by Robert Frost {An American poet; 26 March 1874 – January 1963}
Whose woods these are I think I know.
His house is in the village though;
He will not see me stopping here {He’s not really referring to
stopping in the woods, he’s referring to death}
To watch his woods fill up with snow.
My little horse must think it queer
To stop without a farmhouse near
Between {No hope in his present situation} the woods and frozen lake
The darkest evening of the year. {The subject is experiencing harsh
times and difficulty.}
He gives his harness bells a shake {The horse is restless}
To ask if there is some mistake. {This person’s enjoyment of the
solitude and the lonliness of the woods is not quite complete
because of the horse that is restless at the stop — a reality
check.}
The only other sound’s the sweep
Of easy wind and downy flake.
The woods are lovely, dark and deep.
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep. {The subject is tired and wishes he
could just lie down and sleep, but he has many things to do first.}
