High level AST builders

This namespace contains high level SAGE III AST node and subtree builders.

Building AST trees using raw SgNode constructors is tedious and error-prone. It becomes even more difficult with the presence of symbol tables. This namespace contains major AST node builders on top of the constructors to take care of symbol tables, various edges to scope, parent and so on.
