Thanks for adding this!

Some boring editorial comments:

Instiki has the property that any consecutive letters in math mode are set in math-roman. This is great for long names such as $UnitOfTheAboveMonad$, but gets in the way with the usual habit for some common pre-fixes. In any case, to make tangent bundles etc come out typeset as expected, namely as $T X$ instead of $TX$ there needs to be a whitespace after the $T$:

```
$T X$
```

Apart from fixing that, I have, as usual

added a few more hyperlinks. (Notice that we have not only

*fiber*and*bundle*but even*fiber bundle*:-)added more cross-links (i.e. to and from this entry to related entries, such as

*vector field*,*jet bundle*,*variational bicomplex*)

Added page for evolutionary vector field and explained how the two different definitions are related. This follows a discussion here on this paragraph.
