=====Bitset Operators=====
Syntax:

<code>
    #include <bitset>
    !=, ==, &=, ^=, |=, ~, <<=, >>=, [], =
</code>

These operators all work with bitsets. They can be described as follows:

^ Operator ^ Description ^
|  ''!=''  |returns true if the two bitsets are not equal|
|  ''==''  |returns true if the two bitsets are equal|
|  ''&=''  |performs the AND operation on the two bitsets|
|  ''^=''  |performs the XOR operation on the two bitsets|
|  ''|=''  |performs the OR operation on the two bitsets|
|  ''~''  |reverses the bitset (same as calling flip())|
|  ''%%<<=%%''  |shifts the bitset to the left|
|  ''%%>>=%%''  |shifts the bitset to the right|
|  ''b[x]''  |returns a reference to the xth bit in the bitset|
|  ''=''  |take an unsigned long and put the corresponding bits in the bitset|

For example, the following code creates a bitset and shifts it to the left 4
places:

<code>
   // create a bitset out of a number
   bitset<8> bs2( (long) 131 );
   // you can do bitset<8> bs2; bs2 = (long) 131;
   
   cout << "bs2 is " << bs2 << endl;
   // shift the bitset to the left by 4 digits
   bs2 <<= 4;
   cout << "now bs2 is " << bs2 << endl;
</code>

When the above code is run, it displays:

<code terminal>
 bs2 is 10000011
 now bs2 is 00110000       
</code>
