0.0.4

Changed

• Moved logging methods into a new Log object plus fixed broken fn() method (née currentFn())
  which identifies the currently executing function name.
• Logging helper methods debug(), warn(), and error() methods now call respective
  console methods in browsers that support them.
• Additional fix for issue where init() callback could potentially execute before all
  prerequisite CSS & JS files had completely loaded (esp. when including JS as browser
  globals) by resolving all promises prior to calling _inject().
• Fixed minor JS syntax warnings identified by JSHint.

Added

• Internal Log class containing previous logging methods (as mentioned above), plus new
  startTimer() and stopTimer() methods for performance timing when log_level is set
  to debug.
• Added package.json and Gruntfile.js files for automating syntax validation with JSHint.
