Ichimoku Clouds with Trend Identification

This is another version of the Ichimoku Clouds indicator where I have added logic to evaluate the current chart as either Bullish, Bearish, or Mixed, depending on 4 factors:

1. Is the price above/below the cloud?
2. Is the conversion line above/below the base line?
3. Is the lagging span above/below the cloud?
4. Is the rightmost cloud green/red?

If all conditions point the same direction, then the chart will be labelled "Bullish" or "Bearish". Otherwise it will be labelled "Mixed".

Release Notes:

Main new feature is labelling on a finer spectrum: labels can now not only be "Bullish", "Bearish", or "Mixed", they can now be "Fully" bullish/bearish or have bullish/bearish "Lean".

Also took the opportunity to reorganize the code and refactor for clarity and conciseness, as well as update the comments to be more helpful and informative.
