Simple Neural Network with GPU support

bare bones neural network library with CPU and GPU support.
Only Linux is supported for now.

Install

for both cpu and gpu, the following instructions apply
assuming you are building for gpu:

1. make a build directory inside gpu/

mkdir gpu/build
cd gpu/build

2. You can use whatever build system you want, for ninja:

cmake .. -GNinja -DCMAKE_BUILD_TYPE=Debug
ninja

3. a main executable should now be in your build/ directory
