No description provided.

We need to add tests and possibly implement some methods for result_type as discussed.

Before you start to add tests, you will need to add Distances.jl to the Project.toml by activating the folder and typing ] add Distances.

Awesome, please add a [compat] entry for Distances.jl in the Project.toml. Unfortunately the package manager doesn't add it by default so you have to activate the environment and type ] status to see the version of distances that is installed in your local version of CoDa.jl

[juliohm]

Awesome, we only need some tests now with the distance in action. For example, you can activate the test directory and add the Distances.jl package there as well as a test dependency. Load it in runtests.jl and create a new test file test/distances.jl with the pairwise for example.

Wonderful!
