Improvement: lineage tree information in default output

[elmbeech]

the default PhysiCell output misses information to generate evolutionary lineage trees. it would be good enough when each agent saves information about:

• parent agent_id
• simulation time of birth
• simulation time of death

with this information, things like generation number or generation time can be derived downstream (in Python, R, Julia or whatever your favorite data analysis language flavor).
