[Os-project-managers] Treating NaN

[Kipp Martin]

Hi Guys:

Do we consent to the following:


1) If a user inputs a NaN for an initial value, or does not specify a 
"value" for <initVarValue> we parse this as an OSNAN>

2) If a solver accepts a NaN for an initial input value, we convert our 
OSNAN to the solver NaN. This sounds like it might be tricky.

3) If a solver does not accept a NaN we do not try to think for the user 
and convert NaN to a number the parser accepts. We throw an exception 
and tell the user that this solver does not take a NaN.

Cheers
