Filled up the CART2EUL and EUL2CART matrices for OMC.

The values are saved in the /opt/rtcds/userapps/release/isc/common/projections folder under ISI2SUS_projection_file.mat.

In order to get those matrices we updated the script SEI2SUScoordinates.m with relative coordinates between OMC and the center of the ISI table (from the attached bgchbiai.png and HAM6[...].pdf for x, y, yaw and the solidwork screenshot for z from dcc document D0900295).

x=-64.197mm

y=125.01mm

z=637.08mm

yaw=31 degrees

A new snapshot with safe values has been commited on the svn as well as the ISI2SUSprojection_file.mat file.
