A simple and small service container

Python Service Container
========================

This is a pretty trivial service container with the ability to register Services in it. On
retrieval of an registered service the class got instantiated and behaves as a singleton.

```
from servicecontainer import Service, Container, ServiceInterface

# This is a sample service
class ExampleService(object):
val = None
def __init__(self, param1):
self.val = param1

class ExampleService2(ServiceInterface):
val = None
def __init__(self, param1):
self.val = param1

@classmethod
def asService(cls, parameters):
return Service("testservice2", cls, parameters)

# Create the container
c = Container()

# build an service
s = Service("testservice", ExampleService, {"param1": "param1_value"})

# add the service to the container
c.add(s)
c.add(ExampleService2.asService({"param1": "param1_value"}))

# retrive the service from the container (gots instantiated at this point)
instance = c.get('testservice')
self.assertEqual('param1_value', instance.val)

# list all services
list = c.list()
self.assertEqual(2, len(list))
self.assertEqual(list[0], 'testservice')

# be sure its the same instance
instance2 = c.get('testservice')
assert instance is instance2
```
