Player Model

[tatapuchi]

Create the player model so that we can setup key features such as the upgrade system that costs Player XP.
This should happen once the language feature is implemented, or after all features are ready to go.

Basic members for the model would include:

public int XP {get; set;}
public int Level {get; set;}
public int Grade {get; set;}

//Fields the player is proficient in
//Loaded in when instance of player class is created
public HashSet<Language> KnownLanguages;
public HashSet<Framework> KnownFrameworks;
public HashSet<Tool> KnownTools;
