ZArray is a SIMD vector indexable array C++ class

ZArray is a C++ class which allows vector arrays to be indexed by int-vectors such as int8, int4, int2

Licensed: FREE for commercial and non-commercial use, it is an ENJOYWARE and hope it speeds up your project for you.

Can it be further optimized I am sure! But I am too lazy to do it, feel free to suggest optimizations ideas.

Example usage: 

ZArray<double4v> arr[1024], aVec = 0.0;
for (int i=0; i<1024; i++) {
    arr[i] = double4{ i, -i,  M_PI, -M_PI };
}
int4v idx = { 0, 1, 100, 500 };

aVec = arr[idx];  

// aVec now contains: { 0.0, -1.0, 3.1415, -3.1415 }

// lets change indexes to 10, 20, 30 and 40

idx = int4{ 10, 20, 30, 40 };

arr[idx] = aVec; 

// now the arr contains:
// arr[10][0] = 0.0; arr[20][1] = -1.0;  
// arr[30][2] = 3.1415; arr[40][3] = -3.1415

well you get the idea...
