     Example:
     \code
     QBitArray a(3);
     a.setBit( 0 );
     a.clearBit( 1 );
     a.setBit( 2 );     // a = [1 0 1]
 
     QBitArray b(3);
     b[0] = 1;
     b[1] = 1;
     b[2] = 0;          // b = [1 1 0]
 
     QBitArray c;
     c = ~a & b;        // c = [0 1 0]
     \endcode
 
     When a QBitArray is constructed the bits are uninitialized. Use
     fill() to set all the bits to 0 or 1. The array can be resized
     with resize() and copied with copy(). Bits can be set with
     setBit() and cleared with clearBit(). Bits can be toggled with
     toggleBit(). A bit's value can be obtained with testBit() and with
     at().
 
     QBitArray supports the \& (AND), | (OR), ^ (XOR) and ~ (NOT)
     operators.
