Complex constraints during fitting

Description

Can expressions be entered into the lo/hi table and parsed into meaningful constraints? Right now, a value "7" is parsed to Kn<7. Entering K1+K2 should parse to Kn<K1+K2. A preview would help...

this does work.

It is somewhat confusing, however, to think about which one parses to a ">" and which one to a "<", but it's not too bad.

Biggest problem is figuring out how to get feedback about the constraints, and which ones have been run up to an edge, or worse, which ones were violated.

Also, be careful if we ever decide to make the fit functions threadsafe. Then the textwave of contraints can't be used. It'll need to be parsed into a constraint matrix+vector. See the Curve fitting help for the warning and details.

Help file has been updated to show how these constraints can be entered (with an example).

video help will be added in the future.
