Implement the Binary4 class described by this API.

Make sure to read the documentation for the Bit class.

You do not have to include javadoc comments.

You are given a minimal set of unit tests. The tests are not at all exhaustive. Feel free to modify or add your own tests.

You are also given a main method. The main method should output the following:

    b                   : 1001
    b.numberOfBits()    : 4
    b.getBit(2)         : 0
    b.toDecimal()       : 9
    b.setLeftmostBit(0) : 0001
    b.toDecimal()       : 1
    
    b2                  : 1
    b2.safeGetBits()    : [1]
    
    b3                  : 1001
    b3.shiftLeft(3)     : 1000
    b3.toDecimal()      : 8
