skal 0.0.4

Class based command line wrapper

Introduction
============
Skal is a wrapper for the argparser library to make it easier to write
applications that uses the command-subcommand style, much like git and
heroku.

Basic Usage
===========
Skal can be used on three levels: *class*, *module* and *package*. As this
project is still very young only the class level is implemented as for now.

In file myapp.py:
```python
from skal import SkalApp, command

class MyApp(SkalApp):
@command
def hello(self):
print('hello')

@command
def yes(self):
print('yes')

if __name__ == '__main__':
app = MyApp()
sys.exit(app.run())
```

Running the small program:
```
> python myapp.py hello
hello

> python myapp.py yes
yes
```

Using Custom Arguments
======================
This shows the usage of custom arguments per subcommand:

*Note that @default decorator is not yet implemented!*

```python
from skal import SkalApp, command, default

class MyApp(SkalApp):
"""Help line for application"""

__args__ = {
'-a': {'help': 'Help for a', 'action': 'store_true'},
'-b': {'help': 'Help for b', 'action': 'store_true'}
}

@command({
('-d', '--delete'): {'help': 'Help for d', 'action': 'store_true'}
})
def hello(self):
"""Help line for hello"""
if self.args.a:
print('a')
if self.args.b:
print('b')
if self.args.delete:
print('deleting')
print('hello')

@default
@command
def yes(self):
"""Help line for yes"""
if self.args.a:
print('a')
if self.args.b:
print('b')
print('yes')

if __name__ == '__main__':
app = MyApp()
sys.exit(app.run())
```

Running it:
```
> python myapp.py -a hello --delete
a
deleting
hello

> python myapp.py -b yes
b
yes
```
