+ <br><br>

+<div class="block">Integer wrapper type for unsigned integer values. 
+ <br><br>
+ Java offers no support for unsigned types save from 
+ unsigned conversion methods. This class uses those methods
+ to simulate the unsigned int data type, useful for circuit 
+ truth table encodings.
+ <br><br>
+ When a string representation of an unsigned integer is parsed
+ using Integer.parseUnsignedInt(), an Integer is created using
+ all 32 bits for unsigned magnitude. The integer however is still
+ signed and will behave as such for all arithmetic operations.
+ Bitwise operations can still be performed as they work at the bit
+ level, making this data type particularly suitable for circuit design. 
+ <br><br>
+ TODO in the unlikely event that unsigned integers are natively 
+ implemented in Java, they should be used instead of this class.
+ <br><br>
+ Why are unsigned integers not supported?<br>
