### LocalStorageProvider

#### Operation
* --cache - nothing to do as the images are already in src/
  * not used
* --take - takes screenshots
  * if false => doesn't take act
  * if true => takes act
* --compare - does image comparison (and diff image generation of different in target/)
  * if ( compare && take ) => runs compare => takes act && resolves ref
  * else => doesn't compare => doesn't take act && doesn't resolve ref
* --update - copies the different actual images as reference in the src/
  * if (update && take && compare) => takes act -> compares -> if different => saves act as ref
* --upload - nothing to do
  * not used

### RemoteStorageProvider

#### Operation
* --cache - reads the (applicable for current spec set) ref.lnk files and downloads from imagestore to target/
* --take - takes screenshots
* --compare - does image comparison (and diff image generation of different in target/)
* --update - updates/creates the .lnk files
* --upload - uploads (changed) ref+act+diff images to imagestore
