/** @file opc/container.h
The container.h module has the fundamental methods for dealing with ZIP-based OPC container.
OPC container can be opened in READ-ONLY mode, WRITE-ONLY mode, READ/WRITE mode, TEMPLATE mode and TRANSITION mode.
The most notable mode is the READ/WRITE mode, which gives you concurrent stream-based READ and WRITE access to a
single ZIP-based OPC container. This is achieved without the use of temporary files by taking advantage of the
OPC specific “interleave” mode. \see http://standards.iso.org/ittf/PubliclyAvailableStandards/c051459_ISOIEC_29500-2_2008(E).zip
The TEMPLATE mode allows very fast customized "cloning" of ZIP-based OPC container by using "RAW access" to the ZIP streams.
The TRANSITION mode is a special version of the TEMPLATE mode, which allows transition-based READ/WRITE access to the
ZIP-based OPC container using a temporary file.
