/*
 The aim is to make montages the way we like them.
 Horizontal - grayscale single channels with merge(s) on the right
 Vertical - grayscale single channels with merge(s) on the bottom

 The code got a spring clean in Feb 2020 which allows more channels for the grayscale
 and other colours in the merge(s).

 Notes:
 1. row or column montages are generated (user decides)
 2. Input can be 8-bit, 16-bit stacks/composites or single slice RGB Images
 3. Specify the grouting of the montage (white space between panels)
 4. There's no outside border, and there is an option to add a scale bar (scaling taken from image)
 5. The idea is to compile them afterwards using Montage Compiler

 Batch processing of a directory TIFFs will be added shortly.
