Dependency injection and service container

####Discharge v0.01 - 14.06.2014

• Initial public release, no tests or readme, needs code review and refactoring.
• Service container implemented with some ugly hacks because Dart does not support instantiation of class by its class name in string.

####Discharge v0.02 - 19.06.2014

• Added some basic unit tests (needs more)
• Strings are now encapsulated in double quotes ("). Both single and double quotes were used previously.
• Documentation written in README.md
• Added XML schema for service container config files
