Any thing that requires a unsafe.Pointer to remain will have to use a refcounter.

* Fixed so -race will not complain

* Updated travis to make sure things test with race as well

* Added some tests for Float64Engine and Float32Engine

* Moved to using raw byte slices as per Bryan C Mills' suggestion

* More fixed from just moving to raw byte slices

* Fixed more things for array

* Fixed tests
