#A counter type

"""
Accumulator{T, V<:Number}
Accumulator{T, V}

A accumulator is a data structure that maintains an accumulated total for each key.
The particular case where those totals are integers is a counter.
"""
struct Accumulator{T, V <: Number} <: AbstractDict{T, V}
struct Accumulator{T, V} <: AbstractDict{T, V}
map::Dict{T, V}

## constructors

Accumulator{T, V}() where {T, V <: Number} = Accumulator{T, V}(Dict{T, V}())
Accumulator{T, V}() where {T, V} = Accumulator{T, V}(Dict{T, V}())
