eodev/eo/src/es/eoEsMutationInit.h
evomarc 5508869d00 A full working version of ES is now available in tutorial/Lesson4,
that makes full use of libes.a.
The user guide is in Lesson4 of the tutorial - programmer's guide
will come later.
Plus many small changes here and there

eoESMutationInit. Proxy class that is used for initializing the mutation
operator. It provides an interface between eoEsMutate and the abstract
parameterLoader. It also provides the names for the parameters in this
class as virtual protected member functions.
If you have more than a single ES in a project that need different
names in the configuration files, you might consider overriding this class
to change the names.
