Markdown photo minutes generator

This program helps in creating markdown photo minutes (e.g. for open spaces). It offers the following processing steps:

1. Take a directory structure that contains images of sessions of the following form (names of the directories and file don't matter)

   - session 1
     - image_1.jpg
     - image_2.jpg
   - session 2
     - image_1.jpg
   

2. Convert images as follows:
   • Create thumbnails for each image
   • Create the enlarged image version
3. Save the converted images in the given output directory
4. Create the Markdown document that includes the created thumbnails and links to the enlarged version of the images. The Markdown document is printed to stdout.

How to run the program

The program has three mandatory arguments:

• the directory that contains the INPUT structure
• the directory where the OUTPUT should be written to
• the BASE_ONLINE_PATH where the created images will be hosted

So an example invocation would be

cargo run -- /path/to/input-files /path/to/output-files http://localhost/where-created-images-are-hosted

and would do the following:

1. go through the directory structure in /path/to/input-files
2. created the images
3. save them in under /path/to/output-files
4. print the Markdown document with the links pointing at http://localhost/where-created-images-are-hosted/... to stdout
