Refactor out Analysis module into a sub library

[recursion-ninja]

The Analysis module, while a bit monolithic, is not a dependency of the Bio module. It can be safely moved to it's own sub library.

Once this is done, the unit test suites for this library will need to be moved as well. The integration tests can remain in the domain of the integration-tests executable.

I tried to do this but Bio.Metadata.Dynamic.Class and Bio.Graph.ReferenceDAG.Internal currently depend upon Analysis (Analysis.Parsimony.Dynamic.DirectOptimization.Pairwise and Analysis.Parsimony.Internal respectively). Analysis.Parsimony.Internal is a standalone module to add type safety to node contexts and could easily be moved into the main library. The only thing that Bio.Metadata.Dynamic.Class depends on is DenseTransitionCostMatrix so it seems plausible that we could work around that also but that is code I haven't touched so I may need some input on the best place to put it.

I think we can move DenseTransitionCostMatrix to the pcg-tcm sub-library.

Whilst doing this I also moved out TotalEdgeCost into the analysis submodule (though I believe we don't actually use it whatsoever currently). I also moved Test.Custom.DynamicCharacterNode into analysis for now but it might be worth removing this from our build as more often than not it is just a source of type errors.

TotalEdgeCost is a heuristic cost we'll need later. I think that Analysis is a fine place for it.

Agreed that something needs to be done regarding Test.Custom.DynamicCharacterNode.

Some executable in the utils folder depend on Test.Custom.DynamicCharacterNode. Maybe we should just pull the functionality out of that module and place it in the one or two Main modules in utils where it is needed?

I think that is a good idea, I'll give it a go.

The module and unit tests have now been factored out here: https://github.com/amnh/PCG/commit/31b8fef4704bac5116d946adfb05d681bd2ae532.
