#9:`make_node` accepts all data-/constvars

[wmkouw]

Added make_node method that allows for inline functions applied to datavariables, such as:

@model function sum_datavars_as_gaussian_mean_2()
    a = datavar(Float64)
    b = datavar(Float64)
    c = constvar(0.0)
    y = datavar(Float64)

    x ~ Normal(mean = (a + b) + c, variance = 1.0)
    y ~ Normal(mean = x, variance = 1.0)
end

where two hidden intermediate datavariables are constructed from #1 = a+b and #2 = #1 + c respectively.

closes #9
