Create Testing Mocks

[yujanshrestha]

Agree on an API and create mocks for

• Mesh representation
• Image representation
• Priors representation
• Rasterized weights representation

Rasterizer

• label image size of input image with values of the tetrahedra index each voxel belongs to
• histogram(image[label_image == tetrahedron_id])
• 2^24 voxels per voxel we will need
• 4 double for the value = 32 bytes
• 12 double for the gradients = 96 bytes
• 1 unsigned int per voxel for the label image (tetraheron index) = 4 bytes
• Upward bounds of 2.2 gigabytes
• Also put the image data here to avoid duplication and there is already coupling because of the image size.

Mock will have mesh with a few tetrahedra and images.
