(z<->y): y is now vertical for input/output like in the whole code.
Note that the output and input of the models stayed the same.
The order of the loops over the model should be the same in every function. (The most efficent order)
The models have as fast (n1) directon the z (horizontal) component.
n1/n2/n3 = z/x/y. So with ximage you will see horizontal (n1(z),n2(x)) slices forom top to bottom.

script runs forward and inversion

defined optinal parameters
READREC is now the switch for 0-receiver line / 1-from file / 2-receiver array
using only one receiver specified in the input file is now possible.
if rec array is used checkfd_ssg was checking the wrong input parameters from the .inp files
etc.

+ few addidtional changes:
SRCREC is now the switch to either read from .dat file =1 or use plane wave =2
reduced some arrays (currently unused) to variables

Makefile to install ifos3d with the included library

corrected the text output of the seismograms (didn't match with actual file output)

added progressbar for time stepping and removed timestep output
