[eigen] Typos in "Getting Started"

[Rodney Sparapani <rsparapa@xxxxxxx>]

Dear Eigen developers:

Thanks for such a wonderful library!

I noticed that there are some typos in "Getting Started".
Specifically, in Example 2, the source code uses the float type,
i.e. MatrixXf/VectorXf/etc.  But, the corresponding text refers to
double: MatrixXd/VectorXd/etc.

PS. Has anyone figured out how to "inspire" emacs to
perform syntax coloring/highlighting for the headers?  Since the
headers like Eigen/Core don't have an .h or .hpp file extension,
emacs just shows them as plain text, i.e. using Fundamental mode.
I guess I could brute-force it via ln -s Core Core.hpp, but I
was thinking that someone must have discovered a more elegant
solution.
