Update 'src/app/core/drawers/drawer-aggregator.js'

Fixing midpoint object MiddlePoint: now constructing only one geometric object.
Indentation adjusts: inserted space in all function/method declaration (before open parenthesis) to distinguish it from its use.
Inserted "static static_id" and "this.id" to help debug process.
Inserted some "console.log" to help in debug process.
