 * Returns a library version string associated with the CCM-IO format.

 * In certain cases, when using dynamic libraries, fvm may be compiled
 * with one library version, and linked with another. If both run-time
 * and compile-time version information is available, this function
 * will return the run-time version string by default.
 *
 * Setting the compile_time flag to 1, the compile-time version string
 * will be returned if this is different from the run-time version.
 * If the version is the same, or only one of the 2 version strings are
 * available, a NULL character string will be returned with this flag set.
 *
 * parameters:
 *   string_index <-- index in format's version string list (0 to n-1)
 *   compile_time <-- 0 by default, 1 if we want the compile-time version
 *                    string, if different from the run-time version.

 * returns:
 *   pointer to constant string containing the library's version.
