In this practical you are implementing a research publication system, based on

Java$$s LinkedList.

Implement classes Review, Paper and PublicationSystem that provide the

following functionality:

$$ Class Review:

$$ Stores id$,$ reviewer, score $($number: $1-10),$ confidence $($number: $1-$

$5)$ and summary $($text$)$

$$ Creates a human friendly representation of the class $($i$.$e$.$ toString$())$

$$ Allows a total ordering of reviews $($i$.$e$.$ reviews are Comparable

based on review score$)$

$$ Class Paper:

$$ Stores id$,$ title, authors and review list

$$ Allows reviews to be submitted for a paper if a reviewer is not

already in the review list $($while maintaining the review list in

descending order based on review score$)$

$$ Allows existing reviews to be updated for a paper $($changes to scores

must be reflected in the ordering of the review list$)$

$$ Allows existing reviews to be retracted for a paper

$$ The review list should be printed after every change takes place

$$ Class PublicationSystem:

$$ Contains a main function driving events

$$ Creates three papers

$$ Submits, updates and retracts reviews for each paper so that each

paper has eventually between two and four reviews

$$ Assigns the $$Best Paper Award$$ by calculating the weighted average

score for each paper based on review score and confidence
