Pion multiple Coulomb scattering in the DIRAC experiment (updated version)

This note is prepared not in usual article style, which means that it does not include full needed information, proof of all statements, complete description of the experiment and even References. The note has the main aim to make available the final experimental information about pion multiple scattering in the DIRAC setup. Certainly, the full information is available, but due to its large amount, it takes a lot of time to prepare usual scientific note. Of course, it will be made in the future. Due to unfortunate mistake, which was discovered with help of V.Yazkov, in description of scatter samples position in the program code, some of final results in the original version of the note were incorrect. This updated version eliminates the mistake.
