[GenABEL-dev] new approach for data storage in GenABEL package

 From point of view of a user who uses install.package("GenABEL") this 
version is more convinient because the user does not need to care about 
anything (nothing changed for him). The version with 'suggests' is not 
much different from 'depends' but more flexibale in a case if something 
happens with GenABEL.data.

best,
Maksim
