### Usage example

#### Node
```javascript
var WAValidator = require('multicoin-address-validator');

var valid = WAValidator.validate('1KFzzGtDdnq5hrwxXGjwVnKzRbvf8WVxck', 'BTC');
if(valid)
	console.log('This is a valid address');
else
	console.log('Address INVALID');

// This will log 'This is a valid address' to the console.
```

```javascript
var WAValidator = require('multicoin-address-validator');

var valid = WAValidator.validate('1KFzzGtDdnq5hrwxXGjwVnKzRbvf8WVxck', 'litecoin', 'testnet');
if(valid)
      console.log('This is a valid address');
else
      console.log('Address INVALID');

// As this is a invalid litecoin address 'Address INVALID' will be logged to console.
```

```javascript
var WAValidator = require('multicoin-address-validator');

var currency = WAValidator.findCurrency('xrp');
if(currency)
      console.log('This currency exists');
else
      console.log('Currency INVALID');

// As this is a valid currency symbol 'This currency exists' will be logged to console.
```

```javascript
var WAValidator = require('multicoin-address-validator');

var currency = WAValidator.findCurrency('random');
if(currency)
      console.log('This currency exists');
else
      console.log('Currency INVALID');

// As this is not a valid currency symbol 'Currency INVALID' will be logged to console.
```
#### Browser
```html
<script src="wallet-address-validator.min.js"></script>
```

```javascript
// WAValidator is exposed as a global (window.WAValidator)
var valid = WAValidator.validate('1KFzzGtDdnq5hrwxXGjwVnKzRbvf8WVxck', 'bitcoin');
if(valid)
    alert('This is a valid address');
else
    alert('Address INVALID');

// This should show a pop up with text 'This is a valid address'.
```
