Duplicated string literals make the process of refactoring error-prone, since you must be sure to update all occurrences.
On the other hand, constants can be referenced from many places, but only need to be updated in a single place.
To prevent generating some false-positives, literals having less than 10 characters are excluded as well as literals matching /^\w*$/.
Number of times a literal must be duplicated to trigger an issue can be provided. Default is 3.
