_param_descriptors removal

[andbiz]

Provide documentation through __init__ instead of _params_descriptors

[Alebat]

Should we completely remove _paramsdescriptors? How do we do the sanity check for parameters? **Through assertions in __init_\ Isn't it ugly to put assertions? No, parameters should have correct values**

[Alebat]

I think it is better to split the task in four phases:

• [x] Add the __init__ method to every Algorithm, every optional arg=None
• [x] Set the correct default values
• [x] Add assertions with appropriate messages
• [x] Write docstrings from _params_descriptors

[Alebat]

Now you can use the script! E.g. for InBand(freq_min, freq_max, method, [freq], [psd]) $ python initize.py _Indicator freq_min freq_max method ?freq ?psd Gives as output:

def __init__(self, freq_min, freq_max, method, freq=None, psd=None, **kwargs):
    _Indicator.__init__(self, freq_min=freq_min, freq_max=freq_max, method=method, freq=freq, psd=psd, **kwargs)

@andbiz can you search for "Andrea" in the project? There are some pending fixes. If you can check also the other TODOs please.

• [x] Check that nested algorithm calls of algorithms with parameters are performed within init
