* renamed private members for more clear code * registerExternalBufferID() method to obtain unique ID for withExternalBuffer() * PICoutManipulators::PICoutStdStream enum for select stream (stdout or stderr) * Constructors now accept optional stream * piCerr and piCerrObj macros PIDir::temporary() moved to "mkdtemp" PILog: * now 4 levels * you can set max level * Error writes to piCerr
