Provide a debug mode that gives information about the objects computed in static and dynamic files
For each object in the static or dynamic file, this mode could add:
- the equation number
- for derivatives, the (possibly dynamic) variable(s) against which the derivative is taken
- the human-readable form of the expression (with readable variable names, without temporary terms)
This should also be done for block decomposition mode (in particular, the renormalized equations could be an additional information).
