## Linux compilation

    > mkdir build
    > cd build
    > cmake -DCMAKE_BUILD_TYPE=Debug ..
    > make

## Exercise 1

* Go into directory `Ship` and implement `DecoratedCargo`:
    * It should take a `std::unique_ptr<Cargo>` and has protected getter to this field.
* Implement `Vunreable` class:
    * It should inherit from `TimeObserver` and `DecoratedCargo`
    * It should take additional parameters in C'tor: `Time`, `durability` and `maxDurability`
    * It should simulate time elapsing. Every day should subtract durability
    * It should return price back on current durability of cargo

## Exercise 2

* Implement `Valuable` class:
    * It should inherit from `DecoratedCargo`
    * it should be a template that takes `enum` type of value
    * It should return value based on type (cast it to enum and multiply by current value)
* Try to compile code form `main.cpp`
* You may have some trouble with running code if you don't write a code carefully :) think where is a problem.
