*
* Various routines that handle distributions, value selections and

* env_config -- set config vars with optional environment override
* yes_no -- ask simple yes/no question and return boolean result
* a_rnd(min, max) -- random alphanumeric within length range
* pick_str(size, set) -- select a string from the set of size
* read_dist(file, name, distribution *) -- read named dist from file
* tbl_open(path, mode) -- std fopen with lifenoise
* julian(date) -- julian date correction
* rowcnt(tbl) -- proper scaling of given table
* e_str(set, min, max) -- build an embedded str
* agg_str() -- build a string from the named set
* dsscasecmp() -- version of strcasecmp()
* dssncasecmp() -- version of strncasecmp()
* getopt()
* load_state() -- load the data set configuration details
* store_state() -- store the data set configuration details
