## Detailed Description

This class implements a timer that also implements a tracing functionality.

The timer stores the start time of the timer, for how much time it was set to and when does it expire (start + limit = end). Queries can be made that tell whether the timer is expired, is past an absolute time, is past a percentage of the length of the timer. All times are given in seconds, but as double numbers, so there can be fractional values.

The timer can also be initialized with a stream and a specification whether to write to or read from the stream. In the former case the result of every query is written into the stream, in the latter case timing is not tested at all, rather the supposed result is read out from the stream. This makes it possible to exactly retrace time sensitive program execution.
