StringSet

Constructor

StringSet

new StringSet([args = []])

Based on this code: https://stackoverflow.com/questions/4343746/is-there-a-data-structure-like-the-java-set-in-javascript

Changed the name of functions 'contains' to the name used in ECMAScript 6 ('has').
'remove' has not been changed to 'delete' because in LARA 'delete' is a keyword and cannot be used as a function name
Also, tweaked the functionality of 'add' and 'delete' to behave similarly to ECMAScript 6 Set.

args: Object... - Objects that will be transformed to Strings and used as the initial values of the set. (optional)
