`compass compile` for grunt.js

This is a custom grunt.js task that executes compass compile for you and prints the COMPASS output to grunt.log.write().

Place the grunt-compass folder in the root of your project.
Call grunt.loadTasks('grunt-compass/tasks'); in your gruntfile.

Configure grunt watch to watch your scss files and call the task. e.g.:

watch: {
    files: ['assets/scss/partials/*.scss'],
    tasks: ['compass']
}

Setup the config for compass in your grunt config, or setup a compass config file:
- Option 1: Set the configuration for compass in your grunt.js file:
```
 compass: {
   src: 'assets/scss/partials',
   dest: 'assets/css/partials'
 }
```
  "src" is the folder with sass/scss files. "dest" is the file where the css files will be place.
- Option 2: Setup a compass project
```
 compass install compass
```
Run "grunt watch" and change some SASS files :)

Notice: At this moment this task doesn't work with "grunt" or "grunt compass" it only creates the folders, not the files!
