// RotationIndexer works as following:

// 1. First accumulates spot results from rotation images (only images within a certain stride are included)
|
|
// 2. When a minimum number of images is reached (at least 10 images AND at least 10 deg), indexing is attempted
|
|
// 3. If indexing is successful - lattice is provided that is used by subsequent images
|
|
// 4. If indexing is not-successful - accumulation procedure is continued
