Acquisition improvements

Scanning to memory

User can decide after the scan is made whether to save it or re-take it

Lossless scan compression based on a classifier or user-defined mask (.pcz files with .hdr for meta-data)
Stopping scan after a number of frames is reached or an object is detected

Scan naming improvements

User can easily increment counters in a scan filename. Words ending with a number and separated by underscore can be incremented by cursor keys, mouse wheel or perClass Mira Stage buttons

Fast scanning work-flows

User can fully operate scanning session by perClass Mira Stage buttons (for example: A = scan, B=increment filename counter, C=save)
Stage movements and stage button commands also mapped to keyboard shortcuts.

Dual sensor scanning allowing the user to perform one scanning session resulting in two data sets (VNIR and NIR) on the same objects

Master/worker paradigm: Master instance of perClass Mira can open new "worker" instance
Master controls perClass Mira Stage and one sensor; Worker controls the second camera
User can set each instance specifically for the camera needs and choose different data storage directory
User then interacts with Master instance (to initiate scanning from both instances)
Master and worker can run on the same or different computers
