+NOTES:

+language.py:
+-The entire language is define in language.iset
+
+-language.tokenize() does not yet these data types:
+     - addr11
+     - port_addr
+     - vect8
+
+-16 bit hex strings must be in the format '0xXXXX' or '0xXXX'
+ or they will be interpreted an a 8 bit data type
+
+assembler.py:
+
+- first_pass() doesn't handle any directives apart from 'label:'
+- labels must be defined before they are referenced or second_pass() breaks
+- 16 bit address labels don't work unless the address is actually > 255
+  otherwise tokenize returns them as 'rel8' and the symbol doesn't match
+  anything in iset
