More compiler config options

I got distracted for a bit but just found some time to get back to this...

Some of these hard-coded version numbers need to be extracted as options:

I needed to change vcvars_ver , the others haven't caused any issues so far despite not lining up.

A good idea. Originally I meant to track the latest version of CL, but it turned out NVCC needed the old one. Can I take this to mean that the newest Cuda SDK now supports the latest version of CL? It has been a while since I last did an upgrade.

I think what I will do tomorrow is make those paths a part of compiler options and make a global cfg variable with the defaults which will make it easy to immutably update it rather than having it be copy pasted which is the current situation.

Doesn't seem like it. I was running Cuda 9.1 and had 14.14 toolset installed and it was a no go so originally I just switched over to 14.0. Just tried Cuda 9.2 and it's still not supported. I suppose I should add 14.11 to my VS install at some point but for the time being its easier to just set the option to 14.0.

This should do it.

Now SpiralTypes.fs has the following record that has the defaults on my machine.

let cfg_default = {
    cub_path = "C:/cub-1.7.4"
    cuda_path = "C:/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v9.0"
    cuda_nvcc_options = "-gencode=arch=compute_52,code=\\\"sm_52,compute_52\\\""
    vs_path = "C:/Program Files (x86)/Microsoft Visual Studio/2017/Community"
    vs_path_vcvars = "VC/Auxiliary/Build/vcvarsall.bat"
    vcvars_args = " x64 -vcvars_ver=14.11"
    vs_path_cl = "VC/Tools/MSVC/14.11.25503/bin/Hostx64/x64"
    vs_path_include = "VC/Tools/MSVC/14.11.25503/include"
    cuda_includes = ["cub/cub.cuh"]
    trace_length = 40
    cuda_assert_enabled = false
    }

You can immutably update it like this:

let cfg_testing = {cfg_default with cuda_includes=[]; trace_length=20}

You can access it from a different module as so.

let cfg = Spiral.Types.cfg_default

At the moment cfg_testing is used in the Testing project and the default one is used in the other two projects.

I haven't factored out all the possible compiler options, but I will do so if needed. It is fine if you ask, so let me know if you have any other requests.
