No default cv style or color when not set explicitly

[Joseph Cooper]

I don't know precisely when this changed, but it seems that if moderncvstyle and moderncvcolor are not specified explicitly in the preamble, no defaults are set and no output is the result.

For example:

\documentclass[11pt,a4,sans]{moderncv}
% \moderncvstyle{casual} % style options are 'casual' (default), 'classic', 'oldstyle' and 'banking'
% \moderncvcolor{blue} % color options 'blue' (default), 'orange', 'green', 'red', 'purple', 'grey' and 'black'
\usepackage[scale=0.75]{geometry}
\firstname{Fred}
\familyname{Bloggs}
\title{Test cv}
\begin{document}
\maketitle
\section{Education}
\cventry{year--year}{Degree}{Institution}{City}{\textit{Grade}}{Description} % arguments 3 to 6 can be left empty
\cventry{year--year}{Degree}{Institution}{City}{\textit{Grade}}{Description}
\end{document}

will produce an empty pdf, but uncommenting the two first lines of the preamble will work as expected.

If this is by design, the examples need updating since (as indicated above) they still claim that 'casual' and 'blue' are defaults.
