Enhancement: Create separate distance determination and edge detection pipeline

To independently test each part of our algorithm we need to separate the distance determination and edge detection algorithms. This will require making new implementations of the PipelineExecutor in src/commanline/execution/executors.hpp. These implementation should be called TestEdgePipelineExecutor and TestDistancePipelineExecutor respectively and should only be compiled if a new compile flag called TEST=true. To accomplish this use a similar pattern as decimal. These new pipeline should use similar flags as there respective parts.

Depends on issue #57
