+okay. let's plan it out.
+
+===
+
+Write it in python.
+
+Why? I feel somewhat comfortable in python and don't want to use javascript for this.
+
+===
+
+Break it into steps
+
+1. Initialize the program. 
+2. Create a class
+3. Modules
+  - Parser
+  - Code
+  - Symbol Table
+4. Passes through the program
+  - First pass to create the symbol Table
+  - second pass to parse each line
