modDFS

Given module definitions and reaction information based on a KEGG database, modDFS does a depth first search to find whether a set of KOs are sufficient for completion of a module. For cases where only 1 absent KO would've been enough for module completion, that module is reported to be complete(only lenient). For cyclic modules, completion is defined as having all the module reaction steps present. Again, lenient completion cases are reported. Also, all absent reactions are reported so that a manual inspection of completion can be done for modules that are parially cyclic.
