/**
* "struct strset" is a hashed string set: you can add strings to this
* library, and it stores them as a set of unique strings. You can
* get the size of the set, and you can enumerate through all values.
*
* It is important to note that the strset does not copy the string
* values - it stores the exact pointers it was given in strset_add().
