Need to add a readme doc to guide through setting up dev and basic layout of the repo and maybe deployment

There seems to be some JavaScript input validation that prevents the user from entering dots (.). It's therefore not possible to enter fractional numbers (although pasting them into the field works). Tested in Chrome.

Currently, when input token is switched. The previous estimate is shown unless the user enters a new value. Switching should prompt an automatic update to the swap estimate as well.

Currently, when errors or permissions are denied by users, the state of the UI doesn't properly communicate what may be going on. Will work out better messaging to show this.

Update the UI as shown here:

• "DITTO remaining" -> "DITTO remaining for user"
• Add spaces after available balance: and DITTO remaining for user:
• Add tooltips (please position according to best practices)

Tooltip 1: "Your balance of the select input tokens."
Tooltip 2: "Amount of DITTO you can still receive in this swap until the per user cap is reached."
Tooltip 3: "Total amount of DITTO still available for the incentivized swaps. DITTO is allocated on a first-come, first serve basis."

Copied from website repo # 10 by @chefchansey

Users of the token REB2 token will get an instance of the DittoSwap contract where they can swap REB2 for DITTO at an 1:1 rate. Create a copy of the vampire swap frontend and deploy to: https://ditto.money/reb2swap

Make the following changes:

Change page title to "DITTO redemption for REB2 users"
Remove the "total DITTO left" and "DITTO remaining for user" labels
The smart contract ABI is unchanged. The smart contract for this swap is already deployed and configure at:

https://etherscan.io/address/0xC621C5dc44Eb12cacEBd5959E07D8FeC508f868E

Display the exchange rate for every supported input token somewhere on the page, in the form

1 [INPUTTOKEN] = [n] DITTO

The number of DITTO returned for 1 input token can be obtained by calling

n = getDittoOutputAmount(1 * token_decimals, input_token_address) / 10**9

Current behavior

The user is prompted to approve the input token transfer whenever the page is reloaded or the input amount changes.

Desired behavior

When the user enters an input amount into the form, check if there is already a sufficient allowance of the given input token for the the swap contract. If there is, display the "swap" button. If there isn't, display the "approve" button.

• If the user already has approved some amount of tokens and reloads the page, they should not have to do the approval again to swap the already approved amount or less.
• If the user already has approved some amount of tokens and changes the input amount to a smaller amount, they should not have to do the approval again.
