Correct typo (documentation only)

corrected homophonic spelling error

Thanks @lazaruslarue. While you're tweaking that, what do you think about making it read "Overlay where the sketch features are drawn" or something?

[lazaruslarue]

I think that's an excellent suggestion, which raises a different question:

Which features are drawn on that overlay? It's only a single feature, or a collection of features? It seems from this.features_ that it's a collection. So, how about:

"Overlay where the collection of sketched features are drawn."

?

The "sketch features" are parts of the feature currently being drawn. For a line this is one feature with a linestring geometry and one feature with a point geometry (at the head of the linestring). Once drawing is complete, the drawn feature is rendered elsewhere.

So your doc is correct, but it does give the impression that this is a large collection of features. At most it is a collection of two.

Thanks for the added detail @tschaub. You're right, I didn't understand that this collection was only for the sketching features. Is this correct?

this.sketchFeature_: holds at most two features which (for polygons or linestrings) make up the linestring+endpoint that will be added to the Feature on drawend, e.g. next mousedown.
&&
this.features_: holds the target collection, where sketched features are sent after sketching.

How about: "Temporary overlay for drawing sketch features until they're added to the target layer."

Additionally, while it is clear after spending a bit reading the code, I could definitely see a use case for more documentation about the difference between sketching and drawing features. If there's an issue for more docs about this, I'd contribute to it... or open that issue if it's not there already ;)

Thanks!
