Package metrics

[UFOMelkor]

This PR adds package metrics to PhpMetrics.

Packages are recognized by @package/@subpackage annotations in the DocBlock of a class / interface / … or by the namespace (if not annotations are found).

Current status is

• Add package metrics
  • Number of classes
  • Abstraction / Instability / Distance
  • Incoming and outgoing class dependencies
  • Incoming and outgoing package dependencies
• Add package violations:
  • Stable Dependencies Principle
  • Stable Abstractions Principle
• Reporter
  • Html
    • Package metrics
    • AbstractiontInstability diagram
    • Package relations
    • Package violations
  • Cli
  • Violations
• Add tests
• Handle traits

Any feedback would be appreciated 😊

@UFOMelkor What is the status of this PR? We are really interested in your work here, so if I can somehow help you with finishing the implementation ping me.

@tPl0ch Thank you for reminding me of this PR.

There are two questions that need be answered:

• Do violations about the Stable Abstractions Principle make any sense (and if they do, which distance should be used as limit)?
• How are traits handled related to packages? I tend to handle them like concrete classes.

Apart from this I hope everything is stable now. You could run an analysis of this branch against your code to check whether errors are thrown or not.

@UFOMelkor hard work done 👍

Can you rebase your PR please ? How can we help you to finish ?

[UFOMelkor]

Perhaps you have some thoughts about this two questions …

• Do violations about the Stable Abstractions Principle make any sense (and if they do, which distance should be used as limit)?
• How are traits handled related to packages? I tend to handle them like concrete classes.

About SAP, I'm documenting on it as I'm not totally aware of this. I'll give you my thoughts later. About Trait handling, I think treating them like classes is a good option. Don't forget that horizontally extends doesn't exist in PHP and Traits are a kind of solution to that miss. This tend to understand traits usages as horizontal inheritance, like classes would do if PHP allow it.
