How to config

Grunt provide a simple way to config its tasks, grunt-img follow the same principle:

`js
grunt.initConfig({
img: {

// using only dirs with output path
task1: {
src: 'public/src',
dest: 'public/img'
},

// recursive extension filter with output path
task2: {
src: ['public/src/*/.png'],
dest: 'public/img'
},

// file by file with output path
task3: {
src: ['public/src/logo.png','public/src/social.jpg'],
dest: 'public/img'
},

// single path to optimize and replace all images
task4: {
src: 'public/img'
},

// file by file to optimize and replace
task5: {
src: ['public/img/concert.jpg, public/img/halestorm.png']
},

// filter extension to optimize and replace
task6: {
src: ['public/img/*.png']
}
}
});
