Detailed Description

Str which keeps the data on the heap. We grow the allocated memory only if the copy source is not fitting.

While it should be avoided to use a lot of heap allocatioins in embedded devices it is sometimes more convinent to allocate a string once on the heap and have the insurance that it might grow if we need to process an unexpected size.

We also need to use this if we want to manage a vecor of strings.
