Detailed Description

Concrete subclass of svalue representing the initial value of a
specific region.

This represents the initial value at the start of the analysis path,
as opposed to the first time the region is accessed during the path.
Hence as soon as we have a call to an unknown function, all previously
unmodelled globals become implicitly "unknown" rathen than "initial".
