AtomicMassEvaluation.IsotopeType
struct Isotope
    Z::Int
    N::Int
end

Isotope struct, constructors as follows:

Isotope(iso::Isotope)
Isotope(Z::Integer, N::Integer)
Isotope(name::AbstractString) # parse the name of the isotope, e.g. `Ne20`
AtomicMassEvaluation.IsotopeDataType
IsotopeData

Isotope is a struct that contains the information of an isotope. The information includes the decay mode, mass, binding energy, beta decay energy, and atomic mass.

Base.getMethod
Base.get(data::Ref{Vector{Isotope}}, isoname::AbstractString)

get an IsotopeData from the dataset by name

Base.getMethod
Base.get(data::Ref{Vector{Isotope}}, isotope::Isotope)

get an IsotopeData from the dataset by isotope
