Changing the install method of CLASS : make it much more simpler for the user.

TO INSTALL CLASS FOR THE FIRST TIME YOU HAVE TO RUN CLASS_PATH/Utils/install.sh in the CLASS_PATH folder

+###############################################################
+
+Usage: install.sh [VAR=VALUE] [OPTION]
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help         display this help and exit
+Optional Features:
+  --disable-OMP      do not compile with OpenMP support for evolution 
+                     [default: enable for gcc version >= 4.1]
+  --InstallLib-path=path     Location of made CLASS's libraries [default= $PWD/lib]
+
+Some influential environment variables:
+  CXX         C++ compiler command [default=g++]
+  CXXFLAGS    C++ compiler flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPPFLAGS    C++ preprocessor flags, e.g. -D<special flag>
+
+
+Report bugs to <leniau@subatech.in2p3.fr>.
