Adding a recipe for bison-mode.

This is a major mode for Bison grammars. I'm not the original author,
the original author wrote the major mode in 1998.

I have created a git repository and updated the major mode to conform
more closely to modern elisp conventions. I've fixed the worst build
errors, but I'm aware that checkdoc and flycheck still find plenty of
things wrong with the code.

Add eval-in-repl

Consistent eval interface for various REPLs

This package does what ESS does for R for various REPLs, including ielm.

Emacs Speaks Statistics (ESS) package has a nice function called ess-eval-region-or-line-and-step, which is assigned to C-RET. This function sends a line or a selected region to the corresponding shell (R, Julia, Stata, etc) visibly. It also start up a shell if there is none.

This package implements similar work flow for various read-eval-print-loops (REPLs) shown below.
