This function creates a "LaTeXpackage" object
that provides support for the LaTeX xcolor package.
This allows TikZ pictures to be included in LaTeX snippets.
when calling grid.latex.
The "tikzPicture" package is provided for convenience if the

Two predefined packages are pre-registered
under the names "tikz" and "tikzPicture".
