Detailed Description
SymbolicRegion - A special, "non-concrete" region.
Unlike other region classes, SymbolicRegion represents a region that serves as an alias for either a real region, a NULL pointer, etc. It essentially is used to map the concept of symbolic values into the domain of regions. Symbolic regions do not need to be typed.

Gets the type of the wrapped symbol.
This type might not be accurate at all times - it's just our best guess. Consider these cases: void foo(void *data, char *str, base *obj) {...} The type of the pointee of data is of course not void, yet that's our best guess. str might point to any object and obj might point to some derived instance. TypedRegions other hand are representing the cases when we actually know their types.
