Added overview to creation of final dependency_graph
The new file added in this merge request (dependency_graph.md) provides an overview of how final dependency graph is generated. It includes dependencies and links in the code for better understanding of the code (for a newcomer especially).
dependency_graph.md file includes three paragraphs for three different polaris commands , namely fetch, learn and viz. In each of these sections, I added :
-
The superior or main file which is responsible for importing all necessary methods.
-
Work or importance of almost every file and its contribution to final output.
It solves issue #141
