Unexpected behaviour for Parameter assignment

[Felix Ospald]

 Parameters p;
 p.add("prop1", 1);
 p.add("prop2", 2);

 p["prop1"] = p["prop2"] = 88;

 std::cout << p["prop1"].value_str() << " " << p["prop2"].value_str() << std::endl;

gives "1 88".
There is no copy-construcor or assignment operator defined for Parameter class. e.g.

/// Assignment from Parameter
virtual const Parameter& operator= (const Parameter& value);

is missing.

Stumbled today again over this problem.

solver1->parameters["relative_tolerance"] = solver2->parameters["relative_tolerance"] ;

did not have the desired effect.

solver1->parameters["relative_tolerance"] = (double) solver2->parameters["relative_tolerance"] ;

works.
