json_file_destroy Subroutine

private subroutine json_file_destroy(me, destroy_core)

Destroy the json_value data in a json_file. This may be done when the variable is no longer needed, or will be reused to open a different file. Otherwise a memory leak will occur.

Optionally, also destroy the json_core instance (this is not necessary to prevent memory leaks, since a json_core does not use pointers).
