MODULE NOTES:
See nsStr.h for a more general description of string classes.
This version of the nsString class offers many improvements over the
original version:
1. Wide and narrow chars
2. Allocators
3. Much smarter autostrings
4. Subsumable strings

The subsumestr class is very unusual.
It differs from a normal string in that it doesn't use normal
copy semantics when another string is assign to this.
Instead, it "steals" the contents of the source string.
This is very handy for returning nsString classes as part of
an operator+(...) for example, in that it cuts down the number
of copy operations that must occur.
You should probably not use this class unless you really know
what you're doing.
