[Alephmodular-devel] On CfileDesc and handling navigation

[Br'fin <br...@ma...>]

I've been using my draft as a guide and piece by piece implementing 
portions using or replacing bits of the existing API. (For instance, 
the checked in code now uses iostreams and CFileTypes)

And my own build has begun using a simpler version of CFileDesc as the 
internals to the existing API.

Kind of neat having opening a file be in CFile.cpp. With the platform 
specific bit of converting the platform's internal representation to a 
name compatible with new std:ifstream being handled by the platform 
subclass. :)

I am, however, having distinct second thoughts about creating a new 
CFileDesc for each navigation. Seeing how memory management of the 
various C++ classes is annoying, the prospect of editing a CFileDesc in 
place is appealing to me more and more.

instead of
	GetParent			- new CFileDesc
	GetNamedChild		- new CFileDesc

more of
	clone()			- new CFileDesc
	navigate_up()		- modifies current CFileDesc
	navigate(child)	- modifies current CFileDesc
