readability, refactored most of the code from CreateSkill, which is

Refactored the model classes on a separate package
the model package now contains the data structures and objects to handle
this information, objects are now:

* Skill Model, which is our new vertex in a graph-fashion
* Requirement Model, which are the edges
* Tree Model, which is the graph itself
The main method is now the only one in src
