cynergy 1.1.6

Dependency injection and inversion of control and library for simple service handling

# IOCynergy
Python module for IOC container using dependency injection (uses python 3+ type hints)

## Easy way to initialize your services
```python
from cynergy import container

class TestClass:
pass

class ParentClass:
def __init__(self, test_class: TestClass):
self.test_class = test_class

instance = container.get(ParentClass) # Returns TestClass initialized as singleton

print(type(instance)) # ParentClass
print(type(instance.test_class)) # TestClass
```


## Access to your configuration from any service
```python
from cynergy import container
from cynergy.config import Config, MemoryConfig
from cynergy.attributes import arguments

@arguments(db=Config('db_name'),host=Config('hostname'))
class DbConnector:
def __init__(self, db: str, host: str):
self.db = db
self.host = host

container.initialize(MemoryConfig({
"db_name": "LocalDbName",
"hostname": "localhost"
}))

instance = container.get(DbConnector)

print(instance.db) # LocalDbName
print(instance.host) # localhost

```
** You can implement your own configuration provider (for exmaple you can create DbConfigProvider which provides your settings from the db)

## Manually register special types

```python
from cynergy import container

class Original:
pass

class Other:
pass

container.register_class(Original, Other)

instance = container.get(Original)

print(type(instance)) # Other
```

## Register collection of services
```python
from typing import List
from cynergy import container

class HandlerBase:
pass

class SomeHandler1(HandlerBase):
pass

class SomeHandler2(HandlerBase):
pass

class SomeService:
def __init__(self, handlers: List[HandlerBase]):
self.handlers = handlers

container.register_many(HandlerBase, [SomeHandler1, SomeHandler2])

instance = container.get(SomeService)

print(type(instance.handlers)) # list
print(type(instance.handlers[0])) # SomeHandler1
print(type(instance.handlers[1])) # SomeHandler2
```
