Removed example 'compression_test', as well as 'transforms/adios_{read,write}_all_3D.c' and associated files, as these were basically one-off experimental code that doesn't belong as a full-blown example for ADIOS
Updated NCSU timer linking code
Added some files to various .gitignores, to clean up git status for everyone
Added a more intelligent data sieving decision to the 'identity' and 'aplod' transforms. For identity, point selections only use sieving if the option 'sieve' is passed via adios_schedule_read_param(). For aplod, sieving between component columns is only used if the longest seek sieved over is at most some limit (currently hardcoded as 1MB); if any seek is longer than this, a normal per-component seek-and-read approach is used to get each component.
Cleaned up adios_pin_timestep and better commented the changes supporting it. Also added some utility code to adios_transforms_read.c
Renamed an internal struct member to be more indicative of its meaning
Fixed inconsistency in usage of absolute vs. relative writeblocks by the
transform layer. Now the transform layer will always use absolute
writeblock indexes.
Updated autotools
Fixed bug in transforms test case (was trying to strip a leading / from all variable names in the file, which did not exist, and so it was unable to match any variable name)
Removed extraneous binary in Git
Merge branch 'ncsu-transforms-ccgrid-changeport'

Integrating a reduced set of the changes to the Transforms framework introduced during the CCGrid paper publication.
This largely consists of data sieving improvements in the Identity and APLOD plugins, and the switch to using all
absolute writeblock selections instead of a mix (which was unintended). Other changes are minor, mostly cleanup.
