Configfiler: networks
Parses Flowfile(s), reports for each IP found in networks

flowfiles_scan: find flowfiles in directory, return fh for each
flowfile in directory, 
flowfile_parse: checks header, returns flow

Prototypes for FlowPools:
-------------------------

FLOWPOOL *flowpool_init(char *location);
location could be a single flowfile or directory with flows

flow_t *flowpool_getnext(FLOWPOOL *):
retruns next flow or NULL

int flowpoool_close(FLOWPOOL *);
destroys FLOWPOOL

 struct FLOWPOOL {
    current_flowfile
    number_of_flowfiles
 }

 struct FLOWFILE {
    char *filename;
    LIST_ENTRY(FLOWFILE) entry;
 }
