I've added -ms and -mx options to gij.  These set the initial and
maximum heap size.  We can extend this to compiled code using
properties if we can decide on a nice name for the properties.  Any
suggestions?

Offhand I don't know if the collector has this info.  Newer versions
might have more, though.  (Upgrading is on my to-do list, still.)
Specific suggestions for what to have would be good; we could make PRs
for them so they wouldn't get lost.
