Reorganizing directory structure to implement build system.
Adding basic Grunt build files.
Updated build process to include concat plugin & provide additional meta data.
Re-organized files in the 'src' directory. Library code is in the 'js' directory, files to be distributed with the package, such as documentation and examples, are in the 'pkg' directory.
Split out simple-dashboard.js into separate files, one for each class and updated build files.
Finished the build process using Grunt.  The default target builds to the 'build/' directory while the 'dist' target copies those files to 'dist'. Right now the idea is that 'dist' should only be checked into git whenever a new release is made (except for this initial commit).
Merge branch 'feature/refactor-build' into develop
