11 // BuildingBlocks combines a gauge field, a forward propagator, and backward (or //
12 // sequential) propagators to form the corresponding building blocks (three point //
13 // functions). //
14 // //
15 // history: //
16 // //
17 // There were at least four versions of "MIT" code. Andrew Pochinsky has a c //
18 // version. Dmitri Dolgov has a c++ version. Dru B. Renner has c and c++ versions. //
19 // All were independent and checked against one another. Of course, all were //
20 // developed under the guidance of John W. Negele. The code here is just the //
21 // "Building Blocks" portion of the MIT code. //
22 // //
23 // authors: //
24 // //
25 // Dru B. Renner, dru@mit.edu, 2002 - port of Building Blocks (MIT) code to qdp++ //
26 // //
27 // There are others who have contributed since the code has been migrated to qdp++. //
28 // The cvs log entries indicate these other authors. //
