* Support different length of ScalarPerVector
* Add example of broadcast on fastest axis
* Typo
* Refine fastest example
* Add dimension check
* Modify fastest broadcast example to 3d
* Enforce users give scalarPerVector explicitely
* 1. Add CscalarPerVedctor
2. Not only broadcast on fastest need to set scalarPerVector to 1
* Rename var
* Move IsScalarPerVectorValid() inside IsSupportedArgument()
* Separate GridDesc_M0 into A, B and C
* rename var
* Rename var of length

Caveat
Kernel Timing and Verification
CK's own kernel timer will warn up kernel once, and then run it multiple times to get average kernel time. For some kernels that use atomic add, this will cause output buffer to be accumulated multiple times, causing verfication failure. To work around it, do not use CK's own timer and do verification at the same time. CK's own timer and verification in each example and ckProfiler can be enabled or disabled from command line.
