Symbol Table

1- Must support line numbering and collapsing.
2- Given varname should return uses and/or defs (how to handle use of similar names in different scopes?)
3- Given line number should return variables used and/or defined in that line.

To handle 1, the numbering will be cascaded.
numbers 1,2,3,... show lines of code with all bodies collapsed.
if line m is a while loop, m-n means line n in the body of while.
if line m is an if statement then m-0-i refers to line i in the true branch and m-1-i refers to line i in false branch
Implementation of line numbers will use tuples.
