Wrapper around Distributions.UnivariateDistribution to add support for units, see discussions in e.g. JuliaStats/Distributions.jl#1413.

Currently, you can do things like:

julia> using Unitful

julia> using Distributions

julia> using UnitfulDistributions

julia> const s = u"s"

julia> gau = Normal(55s, 10s)
UnitfulDistribution{Normal, Quantity{Int64, 𝐓, FreeUnits{(s,), 𝐓, nothing}}}(Normal{Float64}(μ=55.0, σ=10.0))

julia> pdf( gau, 30s )
