     Beta version of a clock in base 12.
     by Nayan Sawyer
     started Mar 2022
-    version 0.1.2 April 4 2022
+    version 0.1.3 April 29 2022
     
     Characters are a variation of Kaktovik Inupiaq numerals
     reversed and in base 12 instead of 20. I take no credit 
     for the design.
+    
+    changelog 0.1.3 
+    - Deprecated B12Char by rolling it's code into B12Digit. 
+    Makes for easier to handle arrays, and will hopefully 
+    make implementing the math functionality much easier.
+    It appears that only Clock may need true refactoring to 
+    make the most of this change. B12Int and B12Float seem 
+    to be fine with simply swithing out the reference.
