Cell definitions share fixed_duration boolean for apoptosis death model

[drbergman]

To see this, make the template project and place the attached xml into the config folder. Run the simulation. Output should roughly match the attached video.

Expected behavior: All cells immediately begin apoptosis (apoptosis death rate is set to 100). random_duration cells have a variable time until they are removed. fixed_duration cells all disappear at 2 hours. Both cells have the phase duration set to 2 hours.

Observed behavior: All cells are removed at 2 hours, including the random_duration cells.

Possible cause: PhysiCell_cell.cpp reads in the cell definitions, overwriting the fixed duration field of the apoptosis CycleModel with each one. Unclear how only this field seems to be overwritten and not the apoptosis rates.
