Patch for filib++ of March 15, 2002

Dear German,
please find enclosed a patch relative to the version of filib++ of March 15, 2002. The changes I had to make concern the presence of
using namespace std;
in some filib++ header files. The patch enclosed just removes them and adds explicit qualifications where needed. In general, using directives should be avoided in public include files because there is no way for the user to withdraw them (see http://www.gotw.ca/gotw/053.htm for a discussion of this point). In my particular case, the presence of that directive made compilation of my compilation impossible, since I have to include header files from other libraries and the presence of the "using namespace std" clashes. Keep up the good work
Roberto
