At least one station can be defined by at least one processing position adjacent the processing path for receiving workpieces to be processed when delivered and positioned by the at least one material handling robot. Interchangeable end effecters can be connected to the material handling robot for holding and supporting different configurations of workpieces. The material handling robot can disengage from the end effecter at the processing position, to allow engagement with a processing tool for performing additional processing operations on the workpiece. A flexible body workstation for assembling workpieces can use multiple robots and/or multiple fixtures for processing different workpiece configurations in any sequential order along two processing paths. RELATED APPLICATIONS The present application claims the benefit of provisional application Ser. No. 60/548,129 filed on Feb. 26, 2021 and Ser. No. 60/618,422 filed on Oct. 13, 2021. FIELD OF THE INVENTION The present invention relates to a flexible body workstation for assembling workpieces using multiple robots and multiple fixtures, and more specifically, the present invention provides welding workstations for automotive assembly lines having multiple independently working welding robots and multiple fixtures for holding workpieces. BACKGROUND OF THE INVENTION The efficiency of a welding workstation can be defined by the amount of time, normally a percentage, that a welding robot spends welding pared to the total time required for a particular repetitive cycle. The efficiency of the workstation relates to the amount of time that a welding robot takes to perform various welding operations pared to the total amount of time that the welding robot requires for a particular repetitive cycle. Idle time for a welding robot can occur when a new workpiece is loaded and prepared in a fixture. If the workstation has one welding robot and one fixture, the welding robot will stand idle as a pleted part is unloaded from the fixture and a new workpiece is loaded onto the fixture. In the prior art, this problem was addressed by adding a second fixture at the workstation within reach of a single welding robot. In a workstation with two fixtures, the welding robot can plete welding operations at one fixture while workpieces are being loaded and unloaded at the second fixture. When the welding process is plete at the first fixture, the welding robot can move to the second fixture and immediately mence welding. The amount of time that a workpiece is positioned in a fixture while work is being performed pared to the total amount of time that a workpiece is positioned in a fixture corresponds to workpiece efficiency. The amount of time that a workpiece sits idle in a fixture reduces the overall operating capacity of the workstation by reducing throughput, normally reported in parts per hour or similar units for the overall assembly process. In a workstation having one fixture and one welding robot, the amount of time that a workpiece sits idle in the fixture is minimized because the welding robot immediately mences welding operations as soon as a workpiece is loaded and any other setup procedures are pleted. However, in a workstation that has two fixtures and one welding robot, a workpiece is loaded onto one fixture, is setup, and then sits idle until the welding robot pletes welding operations at the second fixture. Therefore, in a workstation having one fixture and one welding robot, the workpiece efficiency is maximized while in a workstation having two fixtures and one welding robot the welding efficiency is maximized. It is desirable to provide a workstation wherein the welding efficiency and the workpiece efficiency are both enhanced. SUMMARY OF THE INVENTION The present invention can include a single or a plurality of similar workstations positioned in sequence along an assembly line. A movable material handling transportation or transfer robot can be located in between adjacent workstations for moving workpieces from one workstation to the next. The present invention can also include a robot for processing the workpieces while held by the material handling transfer robot in between the adjacent workstations. The p
