Circular references

[Parviez Hosseini]

If I understand the problem right, I think I have a solution.

In the .h files include/import only C headers, and SWARM distribution 
stuff (i.e. <space.h>).  For things like ModelSwarm, etc. put them in the 
.m files. Then there are no circles. The only problem with this might be 
if you're using things like id <ModelSwarm> or ModelSwarm* declaration 
(depending on where you are in version history).

Example

/* Agent.h file */
#include <stdio.h>
#import  <objectbase.h>

@interface .......
@end

/*Agent.m */
#import "Agent.h"
#import "ModelSwarm.h"
....

/* ModelSwarm.m */
#import "ModelSwarm.h"
#import "Agent.h"
