* Port scimax's org facility functions
We provide a hydra to easily use the functions.
By default, the binding to call the hydra is `C-c h`
The hydra is only created if the hydra package is loaded.
* Move org extensions to its own file.
* Integrate revision comments
* Replaced manual placement of src blocks with
`org-element-interpret-data`
* Refactor some functions
* Add a hydra to `jupyter-org-interaction-mode-map`
Only actually define the Hydra if the package `hydra` exists.
* Refactor org extension functions.
* org-extensions: refactor and cleanup
* Remove compiler warnings
* Change condition-case for ignore-errors
* Functions that restart the kernel now work
* Use ivy and avy functions only if package exists
* org-extensions: change hydra bindings
* Match the hydra bindings better to emacs conventions
* org-extensions: improvements and code refactoring
* add where external functions should be found
* take into account empty RESULTS when moving blocks
* org-extensions: use context variable for jumping
* org-extensions: improve jumping to block function
* Set a default variable to specify how many lines of context to show
* Consider the case when a user supplies the nil value
