The interface for eoReplacement is now eoPop<EOT>&, eoPop<EOT>&
(i.e. no const) and the result must be in the first argument in the end.
Hence it is possible to do SSGA and all intermediate replacmeent procedures
The classes derived from eoMergeReduce.h are now in a separate file
The SSGA-like replcaement procedures are in eoReduceMerge.h
A more general replacement can be found in eoSurviveAndDie.h
(it could be made a littel more general - still open for upgrades).
Also some accessors have been added to the eoPop (best and worse individuals)
And include file eo has been updated
