portfolio-entity-manager v1.0.1

Hi! I've made this simple package for frontend intended use, when you deal with frontend state management in some layouts the logic can get messy.

Developing this simple library i thought of every action being "undoable" and the original state going back to original, if you find any problem please create an issue.

addEntity is a function that takes an argument entity (of type T or Y), i designed it this way because sometimes the 2 lists shown in the screen might not share the same exact type.

removeEntity is a function that takes an argument entity (of type T or Y), i designed it this way because sometimes the 2 lists shown in the screen might not share the same exact type.

Internally addEntity verifies first if the entity is already inside the exposed removedEntities array, if it is, the item inside removedEntities is removed and the item goes back to the list it belonged. If the item is NOT inside the exposed removedEntities array we remove the item from the freeEntities array and push it to addedEntities.

If the item is NOT inside the exposed addedEntities array we remove the item from the relatedEntities array and push it to the exposed removedEntities.
