Refactor and improve code

[jcelerier]

• Fix that nothing would build if including puara-utils in multiple files
• Put Calibration code in its own file so that code that does not use eigen does not have to install it
• Add missing default initialization in many places
• Add CI
• Remove some unneeded constructors - in modern C++ if a class looks like e.g.

class Wrap
{
public:
  double min{};
  double max{};
  void f() { blabla; }
};

one can simply create it like:

Wrap w1{-100., 456.};

or even better

Wrap w2{.min = -100., .max = 456.};

C++20 also allows to use () instead of {} for this but I think it is better to use {} as it will refuse to do any conversion that would loose precision unlike () which happily does a ton of implicit conversions)

Thanks for that work @jcelerier.

We can merge as is if it's working (I didn't test it).

However, I'm having second thoughts about creating a utils folder and separating the classes as we did with the descriptors. What do you think?

[jcelerier]

yes, great idea ! I'll do that

[jcelerier]

Ok, did a much more thorough cleanup and adapted the library structure to match more closely current expectations and standards in the C++ community

[jcelerier]

Ok, ci builds on Mac/Win/Linux I think we can safely merge :)
I noticed in the refactor that some functions disappeared though, added a few fixme in the code to bring them back to life @samamou

[edumeneses]

Looks good.

I fixed 1 silly .gitignore conflict

[jcelerier]

ty!

[edumeneses]

@jcelerier and @samamou , I noticed the refactored files don't have the latest editor name.

Perhaps adding you/them to the head comments on each descriptor/utils file is a good idea?

[jcelerier]

hmm to be honest my take on this is that this information is part of git history anyways - adding it to the source files is not adding much value to me.
Likewise for the license file, usually at most nowadays we just add SPDX identifiers: https://spdx.github.io/spdx-spec/v2.3/using-SPDX-short-identifiers-in-source-files/

[edumeneses]

@jcelerier , do we wait for @samamou 's review?

[samamou]

I think i will need to check for the functions that got removed when we were refactoring, I have some time tomorrow @edumeneses

[jcelerier]

build is broken :^)

[jcelerier]

all is green, ACK for me to merge ! congrats :)

[jcelerier]

Edu is it good for you ?
