Description

Most of this work, or at least the computation logic, is already completed in DataScan, so I'll probably make some commits there for extra stats. Each comparison should have an absolute and relative difference between the two. The following methods are needed to complete this:
- Examples of differences in observations
- Absolute and percentage differences between values
- Statistics: mean, std, max, min, stderr(?), t, t pval, r/rsq, iqr, variance

Research direction
Start by reading the existing computation logic in DataScan and the comparison entry point in Compare. Define the output and examples for each comparison, then cover absolute and percentage differences plus the requested summary statistics, including the uncertain stderr item.
