Add Anima::Defaults

[plexus]

Add a way to specify defaults for certain attributes.

Probably not up to your standards, but the basic idea is there. Had some issues running mutant, this will need some more coverage.

There is already a getter for the anima module. AnimaInfectedClass.anima returning an Anima instance.

This code adds an other getter AnimaInfectedClass.anima_defaults, this is kind of aname duplication with the .anima method above, we could avoid in case we refactor the code to attach itself to the Anima module instance. Defaults would be accessed via AnimaInfectedClass.anima.defaults. Resulting in minimum namespace cluttering.

@plexus I just finished a quick code only pass, and had some code flags that we should be able to resolve fairly quickly. As I like the overall idea of backing in default arguments I can offer to do the required fixes by myself or just you deal with the comments of mine. Just tell me how you'd like to proceed.

@plexus Did my comments/review scared you to death ;) ?

You maybe just lost my last comment asking if I should take over.

[plexus]

@mbj yeah this just ended up on the backburner somehow. Wouldn't mind revisiting, but not high prio at the moment. So if you feel like taking over then sure go ahead.

@plexus I'll revisit it the next time I stumble over:

class Foo
  include Anima.new(:a, :b)
  DEFAULTS = IceNine.deep_freeze(
    a: 1,
    b: 2
  )
  def self.new(attributes)
    super(DEFAULTS.merge(attributes))
  end
end

in my code, and seeing myself writing specs for it.

Closing for no activity. @plexus I'm happy to accept this PR when the issues I flagged are fixed. I do not realistically have the time to do this so I'm closing for now to keep the noise in my trackers down.
