A Python implementation of the CGum AST
Generate a CGum AST for a given file as shown below:
program = Program.from_source_file("example.c")
Alternatively, an AST may be produced from a GumTree JSON AST output file,
produced using gumtree parse example.c.
program = Program.from_gumtree_file("example.gumtree.json")
ASTs, or even partial sub-trees may be loaded manually using the method shown
below, where jsn is a JSON file loaded into a Dict object.
node = Node.from_json(jsn)
program = Program.from_json(jsn)
