var statements in program blocks (#256) Adds: - analyzer/LocalVariableScope: tracks local variables created within a given scope. - Instantiated on the stack during semantic analysis, this registers itself with LocalVariableScopes during construction and deregisters itself during destruction. - Detects unused variables during deregistration - analyzer/LocalVariableScopes: this is what LocalVariableScope registers with. - keeps track of the stack of local scopes. - can provide the current local scope, for var statements. Other notes: "Shadowed" variables: this is when a variable in one scope hides a variable in another, like so: var a := 2; if (a) var a := 3; a := 4; endif print(a); // still 2 "debug_variables": We'll use these later when writing debug files. 2020-08-30 01:32:38 -07:00			`#include "LocalVariableScopes.h"`

Properly scope the compiler includes to the Bscript folder. (#360) 2021-02-25 16:53:22 +01:00			`#include "bscript/compiler/analyzer/Variables.h"`
