The default runtime_error() will crash the R session under TMB, which is less than friendly. Return NaN with a warning in the console instead. Whilst not the ideal of selecting first/last values as a default, it's an improvement.

@bthe @willbutler42 The above stops ifmissing being a fatal error at least, so you can at least find these problems without resorting to gdbsource(). |

It'd be nice to be able to say "mean(i)" for ifmissing, i.e. get the mean of i values either from the start or end, depending on which end you fell off. Possibly this should even be the default, for projection / hindcast it'd be the most obvious thing to do.
Whilst this could be relatively easily implemented in C++ (which uses a std::map with an ordering), R doesn't have anything like that available, possibly a condition would have to be generated at compile time?
