Readme is incorrect or unclear about how to get metadata

[Joshua Farray]

Description of getting Width/Height from a JPEG are listed as:

MetaData

You can currently retrieve a JPEGs width and height. This only decodes the JPEGs header information and is very fast.

int width = jpegTransformer.getWidth();
int height = jpegTransformer.getHeight();

These methods exist on the jpegkit.Jpeg class, not the jpegkit.JpegTransformer. I'm not sure if that's an oversight in the intended implementation of JpegTransformer, or if the readme should be describing how to get metadata from a Jpeg object.

Edit: I just realized that there are other bits that seem to refer to the wrong class:

jpegTransformer.crop(cropRect);

JpegTransformer class has cropWithOffsets(...) and cropWithRegion(...) methods. Jpeg class has the crop(Rect) method.
