Branch SP_STL, OpenSP

[Petr O. <pt...@is...>]

Hi,

This is just declaration of intent, not more.

SP is written on C++, and SP demonstrate good language usage.
For 1994. Now we have enough C++ compilers with good C++
implementation, and I see no reasons to keep (buggy) Vector,
String, etc. in the future SP. Ancient code prevent
direct code usage in other C++ projects, except as 'external'
application.

I made branch 'SP_STL' for this task.
Task itself: 'rewrite SP in modern C++, but keep SP structure'.
Indeed this is ambitious target, and I undersand the risk and
complexity of this 'enterprise'.

Big subtasks:

  - replace internal containers by modern STL
  - replace defined 'Char' by OS-supported conversions (? not sure),
    modern char/wchar processing (i.e. NL support in present state).

This (I hope) should simplify code (better support, less code--less
bugs, 'standard' programming techniques), give better performance,
and allow 'embedding' SP into other projects as library with sharing
most of 'standard' code.

Bests,

  - ptr
