Description:
Automated measurement for focusing. After the measurement, the position of the laser along x and z is reset.

Parameters:
- <firstx>, the first x position;
- <lastx>, the last x position;
- <stepx>, the step size along x;
- <firstz>, the first z position;
- <lastz>, the last z position;
- <stepz>, the step size along z.

How to run it:
python Focusing.py --fx <firstx> --lx <lastx> --sx <stepx> --fz <firstz> --lz <lastz> --sz <stepz> --date <yyyymmdd>
