void gmx::test::TopologyManager::initAtoms ( int  count)

Functions for creating simplistic topologies.

These are easy to work with for some kinds of tests.

void gmx::test::TopologyManager::initTopology ( int  numMoleculeTypes,
int  numMoleculeBlocks 

Functions for creating realistic topologies.

Real topologies aren't uniform, so we need to be able to create custom topologies to test against.

Ideally, we'd just be able to push new molecule types and blocks, but the data structures are not mature enough for that yet. The intended usage pattern is to initialize the topology and declare the number of molecule types and blocks, and then call the setter functions to fill in the data structures.
