"""
Creates a GeoModel instance.
This function initializes a GeoModel object, including its grid and interpolation options.
Args:
project_name (str, optional): The name of the project. Defaults to 'default_project'.
extent (Union[list, ndarray], optional): The 3D extent of the grid. Defaults to None.
resolution (Union[list, ndarray], optional): The resolution of the grid. Defaults to None.
refinement (int, optional): Defaults to 1.
structural_frame (StructuralFrame, optional): The structural frame of the GeoModel. Defaults to None.
importer_helper (ImporterHelper, optional): Helper object to import structural elements. Defaults to None.
Returns:
GeoModel: The initialized GeoModel object.
