_nPersonAgeCohortSizes wasn't being initialized anywhere . . . ?

Adding new code to run dengue model under ABC
mend
Merge branch 'master' of https://github.com/tjhladish/dengue

Some objects constructed with new were never being deleted

getPersonByID() was working the way we were using, it, but it would fail in other
reasonable use cases.

Moved contents of Utility.h to its own dengue::util namespace to avoid collisions.

Added back the # of mosquitoes as a fitted parameter to ABC program.
