v2.1.2: addElements and addComponents methods

What's Changed

• Dev/add elements method by @hammzj in #17

Full Changelog: v2.1.1...v2.1.2

Add this.addElements and this.addComponents/this.addNestedComponents

These methods will help remove warnings around declaring this.elements or this.components before initialization. Call these methods in the constructor and assign an object of element selectors or nested component objects, respectively.

Note: In TypeScript, you will need to add public elements: Elements and public components: NestedComponents in order to use them outside of the class!

Removed lodash

Make this a bit more lightweight. It's not needed.
