This is a wrapper class in manipulating bits in C/C++. This
wrapper accepts up to 64 bits of data.

Sample instantiation:

int main(int argc, char* argv[]) { BYTE bdata = 0; XBits bits(&bdata); bits.set(5, 1); bits.xor(4);	// Set bit 5 to 1 // Toggle bit number 4. Turn to 0 // if it‘s 1 & vice-versa
if( bits.check(1) ) { // some code here } else { // some code here } }	// Checks if bit number 1 is on or off
