// Class: Namescheme
//
// Purpose: On-the-fly mapping of the natural numbers (0,1,2,3...) to strings
// using printf-style name-expression generation. A common example is
// using the string 'domain_%03d' to generate strings of the form...
// domain_001
// domain_023
// domain_148
//
// This code was adapted from silo library's namescheme function, where it
// originated as C code hence prolific use of char* instead of std::string.
//
// For examples of use, see the test client, Namescheme_test.C.
//
// Programmer: Mark C. Miller
// Creation: Wed Aug 26 15:34:45 PDT 2009

// Modifications
//
// Mark C. Miller, Thu Dec 18 13:05:54 PST 2014
// Changed embedded strings to be embedded nameschemes.
