Harmonic oscillator model

[ZofiaTr]

It will be possible to do one dimensional harmonic oscillator. I will add the section into the userguide.

Teaser:

[FrederikHeber]

Great. This looks very good!

Is this still simply kinetic energy or already mean loss?

[ZofiaTr]

That's the configurational marginal distribution, i.e. distribution of weight0

[ZofiaTr]

In which section of the userguide can I put it? Simulation?

[FrederikHeber]

Please add it as an extra file, for example +doc/userguide/reference_simulation_harmonic_oscillator.txt+.

There are so many changes to the userguide with this version and it needs to be linked from other parts , too. I'll do this when I merge the branches.

Thanks!

[ZofiaTr]

Great, thanks, I'm on it!

I was also thinking, that it might be very useful if Ben @TeeBee2 could read some chosen parts of the userguide. I suggested some modifications as mentioned in #51 #50 #46 and updated them in the branch Userguide_Samplers, but I might be naturally wrong in some sense, so it would be great to have his opinion. What do you think @FrederikHeber ?

Yes, I am happy to do so but must be next week. So busy here. - Ben

[FrederikHeber]

I absolutely agree that Ben should read the userguide as well. However, this issue is the not the place for this. I'll open a new ticket.

Pushed to Userguide_Samplers

I am not very happy with the quality of the text on the harmonic oscillator. However, I will still merge the branch.

The second code piece was not fully working.
And the explanations are scarce: Why is it a Gaussian probability distibution? It is simple to explain from the mean square loss and "exponential function of energy equals probability".
Moreover, the harmonic oscillator would have been a chance to explain how averages are obtained and in this case to compare to analytically known values. This could form a very nice connection to the analysis sections in the quickstart part of the guide.

[FrederikHeber]

I have added tests on the example code after having extracted them into external files.

Postponing remainder of changes until after v0.9.
