Common manipulations
------------------------
Let's perform some common manipulation on some options:
>>> from tiramisu.config import Config
>>> from tiramisu.option import UnicodeOption, OptionDescription
>>>
>>> var1 = UnicodeOption('var1', 'first variable')
>>> var2 = UnicodeOption('var2', '', u'value')
>>>
>>> od1 = OptionDescription('od1', 'first OD', [var1, var2])
>>> rootod = OptionDescription('rootod', '', [od1])
let's set somme access rules on the main namespace
>>> c = Config(rootod)
>>> c.read_write()
let's travel the namespaces
>>> print c
[od1]
>>> print c.od1
var1 = None
var2 = value
>>> print c.od1.var1
None
>>> print c.od1.var2
value
let's modify a value (careful to the value's type...)
>>> c.od1.var1 = 'value'
Traceback (most recent call last):
[...]
ValueError: invalid value value for option var1
>>> c.od1.var1 = u'value'
>>> print c.od1.var1
value
>>> c.od1.var2 = u'value2'
>>> print c.od1.var2
value2
let's come back to the default value
>>> del(c.od1.var2)
>>> print c.od1.var2
value
The value is saved in a :class:`~tiramisu.value.Value` object.
It is on this object that we have to trigger the `reset`

So by now, we have
- a namespace (which is `config` here)
- a namespace (which is `c` here)
- the access of an option's value by the
attribute access way (here `bool`, wich is a boolean option:
:class:`tiramisu.option.BoolOption()`.
:class:`~tiramisu.option.BoolOption()`.
So, option objects are produced at the entry point and then handed down to
where they are actually used. This keeps options local but available everywhere
and consistent.
The namespace is created, we can set a `read_write` access to the options::
>>> c.read_write()
