/********************************************************
FILE: include/mime.inc
PURPOSE:
Provide functions for handling mime messages.
USAGE:
Use iil_C_FetchStructureString to get IMAP structure stirng, then pass that through
iml_GetRawStructureArray() to get root node to a nested data structure.
Pass root node to the iml_GetPart*() functions to retreive individual bits of info.
