PhysiCell::Cell_Definition possibly memory leaking

[elmbeech]

I get a Segmentation fault (core dumped), if I try to generate a second instance of a Cell_Definition. Reading up on this, this potentially points to a memory leaking.

Minimal example:

1. rest to a fresh PhysiCell installation.

make clean reset
make template

2. add the following line to custom_modules/custome.cpp.

PhysiCell::Cell_Definition cell_defaults_two;

3. compile and run the template project.

make 
./project

I will have to study the code in deep and use a debugger to resolve this issue.
