== Summary ==
Custom code component allowing direct C/C++ code integration with multiple data type support for input and output operations.

== Description ==
The **Custom Code** component provides a flexible interface for embedding custom C/C++ code within visual programming environments.  
It supports multiple data types including analog, digital, complex arrays, images, audio, and specialized types like color and orientation data.  
The component includes hooks for initialization, execution, hardware updates, and supports external libraries and global declarations for complex custom implementations.
