data type mismatch

[lbrichards]

Just trying out test_var and noticing a mismatch between the data type of Variable.address (is actually int) and the test which asserts it is a str.
Also, it would be nice if these were refactored as a suite of unit tests that run automatically.
Nice to see that someone is already implementing DNCL translation to python.

Thank you for seeing my product.
Your suggestion is correct.
I'll refactor and prepare unit test for the better maintenance.

However, meizen/dncl/var.py, val.py, type.py and meizen/test/test_var.py are not used now.
These were wrote at the earliest time on developing, and keeping for sometime to need.
I'm sure that this system can transpile DNCL to Python without any fixing.
