add API

This release adds an API at /api

v0.4

We've had an issues with GINcoin recently where blocks were very slow, and the mining calculator was off because it assumed a block time of 120 seconds. I have fixed this by dynamically calculating blocktime. I am now also calculating block reward versus assuming a static 10 GIN. These are some major steps towards making sure this calculator will be coin agnostic. In the future adding a coin should be as easy as running a daemon and adding a single line.

v0.3

Now implements income in BTC too, now. Next release will feature basic API (requested feature) and will include other coins on the GIN platform.

v0.2

Change the calculation method to use nethash in stead of difficulty, it is lot faster (instant) and only relies on gincoind now, in stead of making calls to GINcoin Block Explorer.

v0.1

The very first release of this calculator. It supports only GINcoin, and it is pretty basic. In the future I would like to support all coins by making it generic, making the webpage prettier, and displaying more useful data.
