Enable snippet functionality

[glenn-operant]

Adds functionality to output a list of available experiments/components, and output a template of them to allow users a starting point.

Also improves our table output, by capturing the size of the term and adjusting the column size accordingly. Or truncating if anything is too long. This preserves a nicely formatted table if anything is too long for the term size.
