/**
 * This class represents an edge server agent.
 * It has capacity to process the tasks sent to it by the device agents. 
 * In addition, it provides the resources it has available
 * In processing a task, it has a cost (measured in pence) that it needs to pay per 10Mb of data processed.
 * It can accept or reject bids from device agents, depending on whether it has the capacity to process the task.
 * Whatever it decides, the message is sent via the marketplace to the device agent.
