Added autotool-support for building musrfit - some additional tests are needed, the old Makefiles are still around

+dnl Autoconf macro to check for existence or ROOT on the system
+dnl Synopsis:
+dnl
+dnl  ROOT_PATH([MINIMUM-VERSION, [ACTION-IF-FOUND, [ACTION-IF-NOT-FOUND]]])
+dnl
+dnl Some examples: 
+dnl 
+dnl    ROOT_PATH(3.03/05, , AC_MSG_ERROR(Your ROOT version is too old))
+dnl    ROOT_PATH(, AC_DEFINE([HAVE_ROOT]))
+dnl 
+dnl The macro defines the following substitution variables
+dnl
+dnl    ROOTCONF           full path to root-config
+dnl    ROOTEXEC           full path to root
+dnl    ROOTCINT           full path to rootcint
+dnl    ROOTLIBDIR         Where the ROOT libraries are 
+dnl    ROOTINCDIR         Where the ROOT headers are 
+dnl    ROOTETCDIR         Where the ROOT configuration is
+dnl    ROOTCFLAGS         Extra compiler flags
+dnl    ROOTLIBS           ROOT basic libraries 
+dnl    ROOTGLIBS          ROOT basic + GUI libraries
+dnl    ROOTAUXLIBS        Auxilary libraries and linker flags for ROOT
+dnl    ROOTAUXCFLAGS      Auxilary compiler flags 
+dnl    ROOTRPATH          Same as ROOTLIBDIR
+dnl
+dnl The macro will fail if root-config and rootcint isn't found.
