/**
Base classes for generic mutations on variable length chromosomes.
Contains addition and deletion of a gene
THey all require a generic mutation for their simple genes
The generic mutations that apply a gene-level mutation to some genes
dont't modify the length, and so are NOT specific to variable-length
Hence they are in file eoFlOr MonOp.h file (FixedLengthOrdered mutations)
