Default sim ages

[RomeshA]

I was running a test sim using ss.Sim() directly (with no arguments) and was puzzled why my simulation had nobody younger than 50, and people that were up to 150 years old. Eventually I realised this is just because the default age distribution is 0-100 and the simulation is run for 50 years. I think this might be a bit confusing for users to encounter in a 'default' sim though?

Agree!

dist = ss.uniform(low=0, high=100, name='Age distribution')

... is not a particularly useful default.

The default distribution if no age data is provided remains:

dist = ss.uniform(low=0, high=100, name='Age distribution')

This issue was closed by #488, which says, "The default maximum age if none is specified is 50 instead of 100." However it's still 100 in code.
