Bug Description

(From Luiz Felippe Rodrigues:) Under very specific conditions, I obtained a negative remnantRadius, making the code crash after trying to compute the squareroot of a negative number (for the remnantCircularVelocity). Crash happens using a modified version of Galacticus - not yet reproduced in the main branch.

I've committed a revision (r315) which should catch problems such as this one and report a suitable error message. This doesn't fix the problem, but should hopefully give some insight into what's causing it.

Seems to be fixed by existing revisions which catch cases where the gas mass in a component drops below zero due to numerical inaccuracies.
