Consider the following code snippet:

```julia
using ForneyLab
g = FactorGraph()
@RV x ~ Bernoulli(0.7)

```

My question is: in what data structure is 0.7 stored? I found that `Bernoulli` is a `struct` by examining the ForneyLab source code. So far, I have not been able to access “0.7” by examining with `g` or `x` from the command line. I am working in Jupyterlab. For example,

```julia
g.variables[:clamp_1]

```

produces

```julia
Variable(:clamp_1, Edges:
Edge belonging to variable clamp_1: ( clamp_1.i[out] )----( bernoulli_1.i[p] ).
)

```

I am simply trying to better understand the internal structure of this package, which I find quite interesting. Thank you.
