Cleanup

Some much needed code cleanup
Versioned dist/ folder for better comparison

v2.0.3 - CacheStorage

With CachceStorage class now we can have a way of caching/uncaching responses saved in Indexed storage.

Support all localforage properties; sanity check key

Added additional support to Index db (localforage) to support all other properites:

• clearAsync() - to clear all keys at once
• lengthAsync() - to get the length of the keys
• getKeyAtAsync() - get a key by it's index
• getAllKeysAsync() - get all keys
• forEachAsync() - iterate over all the keys

Also, added sanity check for supplied key value in all the storage classes. A key 'undefined' cannot be stored anymore.

SessionStorage property issue fix

Using correct properties for sessionStorage and also added .clear() method.

Typescript & IndexDb support

Initial design of centralized const of all methods is bit clunky and hence re-wrote entire library using Typescript (inspiration from repo davutg/client-store) and exposed each storage class in an individual class.

Types of Session and IndexDb properties

Added type definitions for missing Session storage and indexDB properties

Cookies and Local Storage

Though all four types of storage (Cookies, Local Storage, Session, IndexDB) are supported in store.js, the types are only available for Cookie and Local Storage in this first release. In upcoming release all storage types will be type supported.
