Message:

1) Introduce the "applications" directory.
2) Introduce the fixed format (X_WIDTH / Y_WIDTH / P_WIDTH) for processor index in all applications.

Location:

soft/giet_vm/applications

Files:

• . (added)
• transpose (moved) (moved from soft/giet_vm/transpose)
• transpose/main.c (modified) (8 diffs)
• transpose/transpose.py (copied) (copied from soft/giet_vm/transpose/transpose.py)
