metadata doesn't propagate from LateralProfile to Curve

[grzanka]

See this:

>>> from beprof import curve
>>> from beprof import profile
>>> p1 = profile.LateralProfile( [[0,0],[1,1]], generator="sin")
>>> print(p1)
shape: (2, 2)
X : [0.000,1.000]
Y : [0.000000,1.000000]
Metadata : {'generator': 'sin'}
 FWHM = nan None
Center = nan Penumbra = [0.800,nan]
>>> c1 = curve.Curve(p1)
>>> print(c1)
shape: (2, 2)
X : [0.000,1.000]
Y : [0.000000,1.000000]
Metadata : {}

@grzanka I think we removed LateralProfile class, so this issue is no longer valid.

[grzanka]

try to reproduce it in another way - create own class which inherits from Curve and check if it behaves well

[antnieszka]

Still valid:

class TestCurve(Curve):
    pass

def main2():
    p1 = TestCurve([[0, 0], [1, 1]], generator="sin")
    print(p1)
    c1 = Curve(p1)
    print(c1)

Returns:

C:\Python\Python35-32\python.exe C:/Users/ant6/PycharmProjects/beprof/beprof/curve.py
shape: (2, 2)
X : [0.000,1.000]
Y : [0.000000,1.000000]
Metadata : {'generator': 'sin'}
shape: (2, 2)
X : [0.000,1.000]
Y : [0.000000,1.000000]
Metadata : {}

Can you fix it quickly ? If yes, do it, otherwise let's postpone it to next release.

I think this may require some additional code refactoring: https://blog.ionelmc.ro/2015/02/09/understanding-python-metaclasses/
I'll move it to next milestone.

OK
