LightField storage data type

[micdol]

Reading the LigthField code now I see

• __add__
• __sub__
• __mul__

so all math operations which are implemented so far are carried out on re and im representation, yet we store data as amp and phase. This leads to conversion back and forth on each call.

__mul__ can be simply refactored to

self.amplitde *= other.amplitude
self.phase += other.phase

however I see no improvement for __add__ and __sub__.

I'd analyze whether this for of data storage is the best for us.

Ideas:

• [ ] set up counter in each method
• [ ] run some algorithms
• [ ] check how many calls counter registered
• [ ] regardless of the above - measure timing

Also I'd think whether we can just keep phase between [0, 2π) or [-π, π)
