* volgen: reimplement volgenCsaba Henk2010-10-027-2493/+735
| | | | | | | | | | | | | | | | | Generating a volfile occurs in two steps: - Build a graph (ie, glusterfs_graph_t instance) by graph manipulation primitives - Write out the graph to a file by the the graph printing API. Graph builder routines can optionally make use of a "modifier dict", which can contain overrides wrt. volume options. This can be used for a "dry-run" graph generation.
