Add 2001/herrmann2/try.sh + format/typo fixes

Browse Source 
The try.sh script has quite a lot of complicated commands and steps
which makes it much more useful than some others. The .gitignore was
updated for this script.

The README.md file has been format and typo checked.

## Alternate code:
If you wish to use the original version that does not work for all platforms
(and will not even compile with some versions of clang), you can make use of the
[herrmann2.alt.c](herrmann2.alt.c) by running:
```sh
make alt
```
Use `herrmann2.alt` as you would `herrmann2` above.

The original file, used for demonstration purposes, as well as if you want to
see if your system works with the original code, is the alternate version. See
the README.md for details.
Cody also added the [try.sh](2001/herrmann2/try.sh) script which might be more
useful than any other place as the command to try is quite long with C code.
For some reason the original code was missing (presumingly because it had been
added to `.gitignore` by accident) but Cody restored it from the archive.
