Description
Is your feature request related to a problem? Please describe.
\doubleLine is a feature in true bussproofs which is missing in the MathJax version. This is used for writing bidirectional inference rules, e.g.
from
\begin{prooftree}
\def\fCenter{\vdash}
\Axiom$\Gamma \fCenter A$
\doubleLine
\UnaryInfC{$\Gamma, x:A \vdash$}
\end{prooftree}
Describe the solution you'd like
Implementation of \doubleLine for parity with true bussproofs.

Research direction
Start by locating MathJax's bussproofs implementation and the existing inference-rule line commands. Compare the requested behavior with the linked BussGuide2 reference and the provided prooftree example. Done means the \doubleLine command renders the expected double inference line and the example works.
