General verification and clean-up of features C-1 to C-30

[codaich]

• Go through each feature in manual
  • Make sure feature descriptions are clear and complete
  • Rename features to make clearer if need be
• Clean up code for each feature
  • Adjust name and description metadata to match manual if necessary
  • Standardize code formatting
  • Clean up code documentation
  • Adjust code for clarity
• Validate feature implementations
  • Make sure what they calculate matches the manual specification

If rename any of the features, make sure to adjust feature dependency names as well. For reference, dependencies are as follows:

• 52 Most Common Vertical Interval -> Wrapped Vertical Interval Histogram
• 53 Second Most Common Vertical Interval -> Wrapped Vertical Interval Histogram
• 53 Second Most Common Vertical Interval -> Most Common Vertical Interval
• 54 Distance Between Two Most Common Vertical Intervals -> Most Common Vertical Interval
• 54 Distance Between Two Most Common Vertical Intervals -> Second Most Common Vertical Interval
• 55 Prevalence of Most Common Vertical Interval -> Wrapped Vertical Interval Histogram
• 55 Prevalence of Most Common Vertical Interval -> Most Common Vertical Interval
• 56 Prevalence of Second Most Common Vertical Interval -> Wrapped Vertical Interval Histogram
• 56 Prevalence of Second Most Common Vertical Interval -> Second Most Common Vertical Interval
