start working

[cvvergara]

This task is to be done before you actually start knowing pgRouting

• read http://docs.pgrouting.org/doxy/2.3-dev-develop/index.html

Edit this issue and define some tasks to be done from the file. (I added a fist one)

• Installation for developing
• Git Branching Model
• Keep Fork Up to Date

(first plan, then act)
