Small module for reading and writing bitmap images. Currently only 24-bit RGB BMP images is supported.
Initialize a new image with the new function, specifying width and height.
```
extern crate bmp;
use bmp::Image;
let mut img = Image::new(100, 100);
Edit image data using the `get_pixel` and `set_pixel` functions.
Save an image with the `save` function, specifying the `path`.
let pixel = img.getpixel(0, 0);
img.setpixel(50, 50, Pixel{r: 255, g: 255, b: 255});
img.save("path/to/img.bmp");
Open an existing image with the `open` function, specifying the `path`.
let mut img = Image::open("path/to/img.bmp");
```
