Detailed Description

The evaluation block holding the classic polynomial path: function-tree functions (and their derivatives) and/or the compiled straight-line program.

This is the fold of System's historical functions_ / slp_ / eval_method_ machinery into a first-class block, so a System becomes a uniform loop over blocks ("everything is a block"). It owns the function trees, their differentiation, and the SLP, and it carries the system's variable ordering + path variable (the function-tree Jacobian/time-derivative evaluate node trees through them). It is value-in: each Eval/Jacobian/TimeDeriv sets the variables (and path value) from its arguments, then evaluates.

The SLP it can compile itself: SLPCompiler reads exactly the variable ordering, path variable, functions, and derivatives this block owns (see SLPCompiler::Compile).
