Check if graph is dag

WebDAGs. A DAG (Directed Acyclic Graph) is the core concept of Airflow, collecting Tasks together, organized with dependencies and relationships to say how they should run. It defines four Tasks - A, B, C, and D - and dictates the order in which they have to run, and which tasks depend on what others. WebDAG, directed-acyclic-graph, is a graph of nodes in which there are no cyclic references, and therefor has a specific starting and ending point. The dag async method will take an array of edges and resolve a best fit path of execution. It will then iterate over each edge in parallel up to a set amount of threads (concurrency).
