Adding recommendation for constructor arguments

[gbrandtio]

• Recommendation for constructor arguments to be 4 or fewer, as humans tend to be able to hold 4 things in their head at once.
• Recommendation for an alternative approach to use the Builder design pattern, in case it is a fit for the individual use case.

@dimadeveatii could you kindly review this and let me know of your thoughts ?

@gbrandtio nice one, but this is covered in Function arguments section. I don't think we need an additional one for class constructors.

@dimadeveatii thanks for the feedback. Thought that it would helpful to explicitly mention about contstructor arguments as well, since it is missed out many times - as well as the builder pattern alternative.

I appreciate that the function arguments section might be implicitly mean also constructors, therefore closing this PR.
