// General DLL interface notes: 
// 
// In general we can make each member function virtual to avoid exporting 
// each one explicitly (instantiating an object through a factory function 
// is all that is necessary to access the object's functions).  In the 
// Verve DLL we export every member function explicitly to allow us to 
// staticly allocate objects (mainly for the unit tests).  In most 
// applications, developers will only interact with the Agent and 
// Observation classes.  Agents are the only object that can be dynamically 
// allocated, which occurs indirectly through a factory function.

// Use the standard calling convention for Windows DLLs.
