Time delta for logs and replay script
Patch to support optional time delta for logs (vital to produce a more accurate
replay of a log) and added python script for replaying the logs via a named
Testing has been done with a generic USB tty based GPS with the logs replayed.
Thanks Tim. I'll review this shortly.
+ pipe = open(options.pipe, 'w')
That creates a normal file. Use os.mkfifo() to create a named pipe on disk and then stream the data through that. This will avoid what is currently a delayed copy operation.

The pipe I was using to test was originally created with os.mkfifo().
I will extend the script to do check for if a file exists, if so that it is a fifo and if not create the fifo with the os.mkfifo method.

Time delta for logs and replay script 02
Have attached an improved patch that checks specified fifo is valid.
Note this patch also extends the simple-gps-python.py to allow the baud rate to be set. Since my testing is with a serial over USB based GPS setting the baud rate is necessary.
