Got a compiling sast
Changed the syntax for graph literal to "< graph_literals >"
Change in tests according to changes in syntax
Only func left to check in expressions. Weird syntax error.
Expressions have all been semantically checked.
Still have to check statements, and the internal arguments of built-in functions (maybe not the latter, still unsure)
Semantic check compiles through parts that I've checked.
Modified to main function according to syntax
