After a couple of days wrangling ffmpeg code... success! Now able to create the audiograms in multiple sizes, and user can also select the color for the waveform!

Command-line method to extract predominant colors in an image

Front-end done. Updating backend code. Batch job script not modified yet.

Due to increased workload, need to break off the job into separate pieces; backend AG creation script needs to be modified.

Also need to implement some jQuery+Toast approach to notify user once their audiogram has been created.

Adding in some customer-requested features: multi-size, customizable waveform color.

Improved region selection method, with click-to-play option. Lots of progress!

Massive improvement compared to current version!
