Documentation can be built with: ocaml setup.ml -doc

This also fixes two documentation comments that had the wrong syntax.

The 'step' command takes an optional repeat count. Now it stops
stepping and prints the result if the reasoner finishes before
reaching the specified number of steps.

- Use more readable colors and proper spacing
- Differentiate between cores and states by shape
- Add a legend
- Teach debugger to optionally write graph to file instead of stdout

This is easier to type with a standard compose key as opposed as the
arguably more correct "Greek Small Letter Mu".

Otherwise, the debugger would report the reasoner result to be "Sat"
when it should really be "Unsat".

Also shows the correct binary name in the usage output.

- Show a prompt before each input.
- Don't die if the verification of a formula fails. Show an error
  instead and accept the next input.

Array.exists is only available since OCaml 4.03.0 and we need to
support version at least version 4.02.3.

This drops the rule implementation for GML and PML, because they were
relying on GMLMIP which complicated the build process and didn't work
completely. See Issue 19.

GML and PML are still implemented as functors but currently disabled.
To re-instantiate them, an OCaml implementation is needed.

This fixes the warning "the label idx is defined in both types state
and core." by renaming the label to idxS and idxC respectively.

Fixes the syntax of all tests that use R and B as identifiers, which
are keywords now.

Also disables all tests involving nominals as they are currently all
throwing exceptions.

R and B are now keywords and were used as identifiers. Now, r and
b (lowercase) is used instead in the testcases. For consistency, all
other identifiers were lowercased, too.

The CAMLparam0() macro must be invoked at the beginning of a function
that has local variables.

We want to still have the solver for naive unsat propagation
