Conversion script for drs4 became more user friendly

convertDRS4/README.txt

 Application for convertation of binary files acquired by DRS4 to ROOT file.
 
-1. g++ -o read_binary read_binary.cpp -lm `root-config --cflags --libs`
-This compiles read_binary.cpp file and makes object file read_binary.
-2. ./read_binary_DRS4 ./data/rawDataDSR4/file_name.dat
-With the help of the object file it is possible to convert binary file .dat to file .root (which we call raw /home/dariak/NeuRad_tests/data/rawDataDSR4)
-3. read_root.C 
-This script reads raw file and make another file .root with simple analysis /home/dariak/NeuRad_tests/data/dataDSR4
+1. read_binary.cpp complies within makefile (commaned make clean, then make in Neurad_test) and makes object file read_binary in current directory
+2. To convert binary file to root file do:
+./read_binary_DRS4 ./data/rawDataDSR4/input_file_name.dat ../data/rawDataDSR4/output_file_name.root
+!both input and output files should be specified!
