PPCConfiguration refactoring: [6/10]: use #runPass: instead of self-sends. ...in PPCConfiguration>>invokePhases. This is a preparation for removing #invokePhases completely and configuring the compilation via list of phases.

PPCConfiguration refactoring: [5/10]: Commented options in PPCCompilationOptions. So it's more clear for what the option is and how to use it. This is a base for user-documentation as options are meant to be set by the end user.

PPCConfiguration refactoring: [4/10]: introduced a class - PPCPass ... representing a compilation pass over the PPCNode tree. The pass has a common api method: #run:in: which is not used in PPCConfiguration. This simplifed the code and removed some code duplication.

PPCConfiguration refactoring: [3/10]: Moved some sime instvars to context Move some context-related options from PPCConfiguration to PPCCompilationContext. PPCConfiguration now access them wia accessor methods.

PPCConfiguration refactoring: [2/10]: introduced PPCCompilationContext Moved parser class/scanner class instvars from PPCConfiguration subclasses to the context. Made PPCConfiguration to keep an instance of context. This is a preparation for having only one PPCConfiguration-like class.

PPCConfiguration refactoring [1/10]: renamed PPCArguments to PPCCompilationOptions Renamed PPCConfiguration>>#arguments/#arguments: to #options/#options:

Removed unused (obsolete) class PPCCompiledMethod

Added missing #new methods

Fixed PEGFsaState>>isFailure: it is not obsolete, actually.
