At some computers rounding errors occur
The coefficient alpha_prime should be > 0
But somehow the calculation can end up negativ for the coefficient near to the pml
border (should be zero). If that happens it will be set to zero now.

(FP is not initialized as output here)

output changed from stderr to FP

(stderr is not meaningful here)

the free surface functions recalculate the updates on the first gridpoint.
PML needs to be applied here ad the edges.

some changes on Makefile had to be done to outsource functions from the main code

(matches the receiver used by rec_plane

Segy isn't used in our working group and therfore not tested.
Also an segy Input for the obeserved seismograms is missing.
In future options for reading binary and ascii seismograms should be implemented

Updated the seismograms in documentation
with seismograms from the updated script
and cleanup of old figures

- slice2D_toy_model.m now reads source and receiver positions and plots them if the positions are located in the current 2D slice
- One figure in the manual had old coordinate system (fixed)
- removed old figures in git

- old file name: seismo1_toy -> changed to seismo_trace_toy

- input data of folder /par/su and /par/su_obs resp.
- using function su2matlab instead of binread to read binary files
- added layout (legend, text boxes for the components)
- divided variable t by 10^6 to get time in seconds

exportfig is an extarnal matlab script

And a few adaptions to existing scripts

Still changes to be done in toy example chapter.
(figures with rotated coordinate system)
