Well I didnot find replace_all in usage of the bib. Now that you tell me, i 
can find it.  
But here I see no way to tell replace_all that my strings are not seperated by 
spaces but +*() etc.
         a+3*sin(b) 

So what I had expected is like this:
string str="a+3*sin(b)";
replace_all(str,"b", "Beta", "+*()")  // now str="a+3*sin(Beta)";

Perhaps a task for tokenizer(?)

I'll have a look
