- in preparation for adding an optional '-reconstruct' to a few utilities
re-use as -lreconstruct library
- move related stuff there too
src/decompositionMethods/decompositionMethods
-> src/parallel/decompositionMethods
- added missing namespace qualifiers
- The capitalization is consistent with most other template classes, but
more importantly frees up xfer() for use as method name without needing
special treatment to avoid ambiguities.
It seems reasonable to have different names for transfer(...) and xfer()
methods, since the transfer is occuring in different directions.
The xfer() method can thus replace the recently introduced zero-parameter
transfer() methods.
Other name candidates (eg, yield, release, etc.) were deemed too abstract.
