Sig Eq Paper model units error

[mayork]

This is the print out when I run @mopg signomial equality paper solar hale scripts

eginning signomial solve.
Solving took 4 GP solves and 0.228 seconds.

it looks like the model solves and then a unit error is thrown while creating the solution dict? I'm not sure how to proceed, but would really like to analyze this model to see if the atmosphere linearizes the same way as my atmosphere model. @bqpd thoughts?

the code is in PR #83

[bqpd]

It's a gpkit bug, closed in https://github.com/hoburg/gpkit/pull/876

[mayork]

forgot to mention I changed the SignomialEqualityLinTrust in the solar hale to be SignomialEquality and ran this on gpkit master

[bqpd]

Yup, did that.

[bqpd]

Will merge to master once tests pass.

[bqpd]

@mayork, try now.

[mayork]

it works, thanks!
