Task 1
Goal:
- Familiarise with development environment
- Simple class syntax

Task:
Implement a Vehicle class. Every Vehicle is characterised by a current speed (integer) and a maximal speed (integer). A Vehicle has the possibility to store maximum 5 features (string). Besides the necessary constructor(s), setters and getters, a Vehicle has some extra methods:
+ bool changeSpeed(int delta): adds delta to currentspeed if new value is in range [0..maxspeed], returns true if currentspeed has been updated.
+ void addFeature(string): adds string to featurelist if space is still available
+ bool removeFeature(string f): removes feature f from featurelist if f is found, shift content of all following features. Returns true if string has been removed.
+ std::string info() which returns a string like
The vehicle is running at speed [currentspeed]
and has [nr. of features] features:
* [feature1]
* ...

Create a test application which instantiates some vehicles, change speed, add and remove features and show output of info() on different situations to check the implementation
