-Sample usage::
-
-  >>> base20 = BaseConverter('0123456789abcdefghij')
-  >>> base20.encode(1234)
-  '31e'
-  >>> base20.decode('31e')
-  1234
-  >>> base20.encode(-1234)
-  '-31e'
-  >>> base20.decode('-31e')
-  -1234
-  >>> base11 = BaseConverter('0123456789-', sign='$')
-  >>> base11.encode(-1234)
-  '$-22'
