Viz/graph of tasks

[zifeo]

whiz --graph should output an ascii visualisation of the tasks and their dependency. Format is free but should support large graphs.

Have a working solution here. Possibility to view the graph with box-character as well. For now I've just made a binary crate that parse yaml file from command line and generate the correspondent graph. The file has a structure similar from the resolved whiz tasks dependency list in main function:

task_1:
   depends_on:
       - other_task
       - antother_task
task_2:
    depends_on: []
#...

In the upper bar there are the tasks that haven't dependency with the others, in the bottom you have the dependent tasks graph.

I've also made a function for generate casual big dag for checking the representation. I've used a binary crates that helps draw from nodes and edges lists termgraph. There are others solution that I've found :

• a perl mdule called Graph-Easy that allows to get ascii representation parsing a dot file.
• petgraph and graphviz-rust. The last one needs graphviz binary already installed in order to parse the graph into the .dot file, but neither of those crates has an ascii representation Waiting for feedback!
