Compute mean expression for each triad for each combination of factor levels.

1	triad_expression_means_by_factors(expression, metadata, homology, factorList)

`expression`	A data frame of expression values, in which each column is a sample, and each row is a single gene.
`metadata`	A data frame containing metadata for each sample.
`homology`	A data frame of metadata about each triad. Include which genes make them up on the A, B, and D genomes.
`factorList`	A list of column names that exist in 'metadata' (as strings) to use as a factors.
