Quick Overview
--------------
javascript
var quantize = require('quantize');
var arrayOfPixels = [[190,197,190], [202,204,200], [207,214,210], [211,214,211], [205,207,207]];
var maximumColorCount = 4;
var colorMap = quantize(arrayOfPixels, maximumColorCount);
```
* arrayOfPixels - An array of pixels (represented as [R,G,B arrays]) to quantize
* maxiumColorCount - The maximum number of colours allowed in the reduced palette
##### Reduced Palette
The .palette() method returns an array that contains the reduced color palette.
```javascript
// Returns the reduced palette
colorMap.palette();
// [[204, 204, 204], [208,212,212], [188,196,188], [212,204,196]]
```
##### Reduced pixel
The .map(pixel) method maps an individual pixel to the reduced color palette.
```javascript
// Returns the reduced pixel
colorMap.map(arrayOfPixels[0]);
// [188,196,188]
