## Detailed Description

Prints snapshots of fitnesses to a (new) file every N generations.

Assumes that the parameters that are passed to the monitor (method add in eoMonitor.h) are eoValueParam<std::vector<double> > of same size.

A dir is created and one file per snapshot is created there - so you can later generate a movie!

TODO: The counter is handled internally, but this should be changed so that you can pass e.g. an evalcounter (minor)

I failed to templatize everything so that it can handle eoParam<std::vector<T> > for any type T, simply calling their getValue method ...
