 While vector<> has an 'explicit' on its constructor with unsigned
 integers, bounded_vector does not.  This means the following ugliness
 compiles:
 bounded_vector<double, 2> v;
 v = 2; //This SHOULDN'T compile if the patch is applied.  Using cast to
 unsigned int.

 Also, while vector<> has a constructor that takes a size and then a value
 to initialize with, bounded_vector does not. I added in a constructor for
 this operation and for consistency, so the following compiles:
 ublas::vector<double> v(2, 1.8);
 ublas::bounded_vector<double,2> v(2, 1.8); //Now consistent.

 .... this became necessary when I was doing programming for generic vector
 types and wanted to construct with an initial value.
