[Somelib] Current design concept

[Thomas M. <tma...@ze...>]

Here is the layout for what I'm currently working on, not all ideas have
been completely fleshed out.

BasicDynLib - an abstract base class for loading dynamic libraries.
Specific types (linux, windows, hpux, ...) are hidden from the user and
selected by defining the correct symbol in UserConfig.h.  BasicDynLib*
newDynLib() allocates the selected derived class.

SOMELibFactory - Manages loaded libraries.  Dynamic libraries must have
a function vector<SOMEClassInfo>& RegisterClasses() to return
information about classes available for use within the library.  This
will allow packaging of multiple classes within one library.

SOMEClassInfo - I'm not sure exactly how this class will work but it
will contain the class name, a category/purpose, and (if possible, I
think it is) functions for creating instances of the class.  I think
this would eliminate the need for base classes, like Karl's did.
