Issue #14 - Method and variable with same name and recursion.

I have changed Member.java: 
```
    @Override
    public String toString() {
        StringBuilder stringVersion = new StringBuilder();
        stringVersion.append("[name: " + name + ", type: " + type
                + ", references: [");
        for (Member m : this.referencedMembers) {
            stringVersion.append(m.name + ";");
        }
        return stringVersion.toString();
    }
```
