 # QFixedSizeMatrix
 Some C++11 optimization/template tests

+I just finished a training about test driven development and wanted to test it quickly with a very small project.
+
+I was trying to implement an array like container with helper functions to rotate it (maybe useful in some chess/tetris game?)

+I also wanted to know more about templated classes and functions and about their performance at runtime.
+Looks like the compiler removes all my function calls and just places the resulting integers into the executable:
