There is a clear need to allow user's to create multiple wallets.

**Describe the solution you'd like**
Allow users to create multiple wallets

Need to track the amount of wallets in the reducer and when the user wants to switch wallets we can just change the derived path.

Every wallet name must map to an index in the masterNode.derivePath

``var HDNode = require('ethers').HDNode;``
``var mnemonic = "12 words";``
``var masterNode = HDNode.fromMnemonic(mnemonic);``
``console.log(masterNode);``
``var wallet1 = masterNode.derivePath("m/44'/60'/0'/0/0");``
``console.log("wallet 1 - " , wallet1);``
``var wallet2 = masterNode.derivePath("m/44'/60'/1'/0/0");``
``console.log("wallet 2 - " , wallet2);``

Start by tracing the reducer and the ethers HDNode. Review the BIP-0032, BIP-0039, and ethers HDNode resources, then verify how wallet names map to masterNode.derivePath indexes. Done means users can create multiple wallets, the reducer tracks them, and switching wallets selects the corresponding derived path.
