Updated to allow multiple definition terms and definitions per term
<Term>::<definition>
<Term>::<definition1>::<definition2>
::<definition3>
```
**Example** ::
::V3 uses HTML *definition lists* to create "lists" with hanging indents.
::Three
I'm a term::Four
**<u>Hello</u>**::I\'m a different
::List
:
```
This should match more economically and in line with marked
recomendations as well as not allow whitespace ( \s ) at the beginning
or end of a sub or superscript mark. Additionally, a failure in having
mixed sub and supers on the same line was corrected.
Uses ^^ for superscript and ^^^ subscript as wrappers in the same
pattern as italics and bold ( * and **, respectively)
Adds editor hot-keys and sytax highlighting. (CTRL-6/CTRL-7)
Exact values may not be ideal. Short of the suggestted overloading of ~,
I didn't see a better option for the delimiter.
