pgr_sequentialVertexColoring GSoC-2020 Week 5

[krashish8]

• Modified implementation of pgr_sequentialVertexColoring and pgr_depthFirstSearch
  • Removed seq column from the output of pgr_sequentialVertexColoring.
  • Sorted the edges of both pgr_depthFirstSearch and pgr_sequentialVertexColoring in an ascending order of their id before creating the graph, so that always the same set of rows will be returned.
  • Sorted results in an ascending order of the node id.
• Edited documentation of pgr_depthFirstSearch
  • Added "experimental" in index, edited "See Also" section
  • Removed the "Vertex Out of Graph" section.
  • Added some points in the description section.
• Completed the documentation of pgr_sequentialVertexColoring - pgr_sequentialVertexColoring.rst file.
  • Added docqueries for the documentation using sample data.
  • Included the docqueries in the documentation file (.rst).
  • Generated documentation locally and deployed it for preview.
