Possible typo in thresholds?

[mkborregaard]

I was reading the code for thresholds, and wondered whether this line

https://github.com/mrmaxent/maxnet/blob/master/R/thresholds.R#L7

should not contain 2:(nknots+1) instead? The current code looks strange.

I believe you're correct. Fixing it now.

Added parenthesis to fix the issue.
