I was coding earlier this week, but my brain was so foggy I ended up not knowing what I was doing. After a few days break, I've cleaned up the mess, which took hours. Changes: * Variables can be assigned * Added new value types as placeholders * Added 'compare' and 'assign' to the AST * Added duplicate opcode * Added functions to copy and free values * Max name length is 255 chars * Compound assigns are squeezed into one word To be completed: * Tests for this commit's changes * Compound assignments * Variable access
