* Fix shifting over `--`: don't throw errexit
Fixes#21
* Add error trapping (including Ctrl-C) info to FAQ
Closes#47
* Add backtracing to help localize errors
- Fixes#44
- Backtracing is turned on when the debugging `-d` flag is passed,
otherwise backtracing function defined but signal trap not set.
- Update main-help fixture due to moving trap
* Untabify main.sh
Might be a controversial move, but I loath tabs...
* Add checks for tab chars and trailing whitespace
- Update poor-man's style enforcement script to check for these
violations
- Better document style guidlines in README with small tweaks
* Add a magic variable to indicate if being source
if `__i_am_main_script=1 #true` then `main.sh` called directly

If the description of an option contains the single word sentence
'Required.' it is understood as a required argument and automatic
validation will make sure that it is set or end the script by calling
help.
Alternatively, if the argument within the __usage string is {arg}
instead of [arg] it is understood as a required argument and automatic
validation will make sure that it is set or end the script by calling
help (even if 'Required.' is not in the description).
Closes#22
