Perform cross-validation for the ranking.

This function reoptimizes the ranking leaving out one of the original reference genes at a time.

validate(ranking, reference_gene_ids, method_ids, progress = NULL)

`ranking`	The ranking to validate.
`reference_gene_ids`	The reference gene IDs whose ranking should be validated.
`method_ids`	IDs of the methods that were used.
`progress`	An optional progress function that should accept a single value between 0.0 and 1.0 for progress information.

A validation object with the following items:

validation: A data.table containing percentiles of the comparison genes from the original ranking as well as their validation.
mean_score: The mean score of the genes.
mean_percentile_original: The mean percentile of the genes in the original ranking.
mean_percentile_validation: The mean percentile of the genes when optimizing without themselves.
mean_error: The mean absolute error.
