          Small String Optimized String

====================================================

The Small String Optimized (SSO) string data-type attempts to reduce the number

of heap allocations that happen at runtime. If a string is less than 23 bytes

on 64bit it can be stored directly in the object, avoiding a dynamic allocation.

There exist two modes for each String, a short string - and a long string mode

in which the dynamic memory is managed using Nim's destructors. The

implementation is based on clang's std::string class. This technique might

improve runtime performance and reduce fragmented memory where this is most

needed i.e. on embedded systems.
