736267cf6b Added support for additional tensor operations: 
* comparison (<, <=, ==, !=, ...)
  * selection
  * nullary ops such as random or constant generation
  * misc unary ops such as log(), exp(), or a user defined unaryExpr()
Cleaned up the code a little.

84cb1d72b8 Removed IACA-defines 
This caused redefinition warnings if IACA headers were included from elsewhere. For a clean solution we should define our own EIGEN_IACA_* macros

c0f2cb016e Extended support for Tensors: 
* Added ability to map a region of the memory to a tensor
  * Added basic support for unary and binary coefficient wise expressions, such as addition or square root
  * Provided an emulation layer to make it possible to compile the code with compilers (such as nvcc) that don't support cxx11.
