cryptowatchR 0.2.0

• Now get_markets() works with all routes (summary, summaries, price, prices, trades and orderbook, orderbook/liquidity and orderbook/calculator).
• New functions which are wrappers around get_markets(): get_ohlc(), get_trades(), get_current_prices(), get_summary(), get_orderbook(), get_orderbook_liquidity() and get_orderbook_calculator()
• New feature to use your own API key for all functions. See argument api_key in functions.
• New feature to show allowance (costs per request, remaining credits). See argument allowance in functions.
• markets() is now deprecated and will be removed in a future version. Use get_ohlc() instead.
