This requires an agent variable named 'id' of an integer type (signed or unsigned) to generate the appropraite function If an initial states file is provided, the first id assigned by the generate_<agent>_id() function is the maximum+1. The user can specify a start number if desired. The value is synchronised between the host and device where appropriate, through memcpy when appropriate. Device concurrency is handeled using atomicAdd

Constrained to only work for agents with a variable 'id', of a singular integer type (short, int, long long) which may or may not be unsigned.
The maximum id from the initial states file is found and used as the first value available in an init function.
The current next id is maintained through host/device memcpys and state tracking to ensure that the correct value is available at the appropriate location.
i.e. for an agent named 'Agent' the function
generate_id_Agent()can be called in a host or xagentOutput device function to generate a new identifierCloses #247
Function / variable names can be changed if desired.
