     * Sort the list of imports into groups.
     *
     * 
     *
     * Consider that we have the following list of imports as argument:
     * 

     * 
     * import java.util.List;
     * import com.github.javaparser.ast.NodeList;
     * import com.github.javaparser.ast.ImportDeclaration;
     * 
     *
     * 
     *
     * And we want the imports to look like this: (Note the spacing between imports)
     * 
     * import java.util.List;
     *
     * import com.github.javaparser.ast.NodeList;
     * import com.github.javaparser.ast.ImportDeclaration;
     * 
     *
     * 
     *
     * In this case, we have two groups of imports. The first group contains only import for java.util.List,
     * while the second group contains NodeList and ImportDeclaration.
     * 
     * For this example this method should return 2 groups in the list, and the first group should have
     * exactly 1 import, while the second group should have 2 imports.
     *
     * @param imports The imports to be ordered.
     *
     * @return The group of sorted imports.
