#7 superglobal objects

[Jan Ringoš]

TODO:

These are actually two proposals. One is for "lib" and
would include introducing and object lib::share, that
would allow different processes creating the same
"share" to share data by simple reaing or assigning. I
have this partially implemented in another project, so
if it turns useful it will make it into the library.

The second part would be creating an abstract base
class that would made a object "superglobal" ...
meaning that the object would be created in first
instance of the process, and destroyed when the last
process is closed.

Experimental thought.
