[.cimg: Array subset operator for cimg objects
Description
Works mostly just like the regular array version of x[...], the only difference being that it returns cimg objects when it makes sense to do so. For example im[,,,1] is just like as.array(im)[,,,1] except it returns a cimg object (containing only the first colour channel)Usage
## S3 method for class 'cimg':
[(x, ...)
