#Currencies

A simple library for currency symbols, names, and exchange rates.

##Usage

``js
var currencies = require('currencies');
`

Initially you have just a map of currency names and symbols, which you can get or set:

`js
currencies.get('USD').symbol === '$';
currencies.get('PLN').name === 'Polish Zloty';
`

###get

Without an argument, returns the complete currencies map

`js
currencies.get('USD')
currencies.get();
`

###set

Set a currency's rate (USD-relative) yourself

`js
currencies.set('EUR', 0.77);
currencies.set({
EUR: 0.77,
AUD: 1.05
});
`

###update

Calling this function will update the internal currencies map with current exchange rate, using data from European Central Bank.

`js
currencies.update(function(err, newCurrencies) {
newCurrencies['USD'].value === 1
});
``
