Deprecation

Bio.jl is old and deprecated

Hi there! There have been incidents of confusion where newer users have tried to install and run an old and deprecated BioJulia package called Bio.jl, or they have not known which package(s) they need to install in order to start working. So I'd like to take the opportunity to clear this situation up and perhaps put out a clearer explanation, of why Bio.jl exists when there are other packages with overlapping functionality.
