Trace tags for dumping the decision tree in org-mode format (#2871)
This would add tracing options to print the decision tree in [org-mode](https://orgmode.org/) format which can be viewed with emacs or [vim-orgmode](https://github.com/jceb/vim-orgmode).
In the raw format, the number of asterisks denote the decision level of a decision, and within a propagation node, the number of spaces denote the level. Most viewers render the asterisks as indented bullets.
There are some options for controlling verbosity:
`dtview` - prints the decisions (basic option)
`dtview::command` - also prints smt-lib commands as they're issued
`dtview::conflict` - also prints conflicts
`dtview::prop` - also prints propagations
Example usage:
`cvc4 -t dtview -t dtview::command -t dtview::conflict -t dtview::prop <example smt2 file> &> example-trace.org`
The resulting file when opened with an org-mode viewer has collapsible nodes, where "..." marks a node with children.
