Adds support for var statements at the global level. Adds: - analyzer/Variables: keeps track of the variables in scope (either local or global). - ast/Identifier: AST node for an identifier. - The optimizer will replace constant identifiers with their constant value (in a later commit). - The semantic analyzer will set the variable field for local or global variable identifiers. - ast/VarStatement: AST node for a var statement. - A single var statement will generate one VarStatement per variable declared. - model/Variable: Describes a variable, including its index within its scope.
