user-defined context-aware variables, functions & classes suggestion

[kammeows]

The file parseCodeVariables.js is responsible for analyzing the Abstract Syntax Tree of the user's code. As it walks through the AST, it collects and organizes information into maps:

• p5ClassMap: Keeps track of p5.js-specific classes (like PVector, Color, etc.).
• varMap: Stores all variables found in the code.
• varScopeMap: Keeps track of the scope (e.g., global, local) of each variable.
• userFuncMap: Records user-defined functions.
• userClassMap: Records user-defined classes.

Once this information is gathered, it is passed to contextAwareHinter.js, which provides the code suggestions based on the current context in the code editor.
