Generate Random, Non-Overlapping Partitions of Indices with Reference vs Rest

1	sample_partitions_by_half(n, fraction, warn = TRUE)

`n`	Number of elements to partition.
`fraction`	A numeric of length two in (0,1/2] specifying the size of each partition relative to `n`, where the first element specifies the "reference" partition and the second the "test" partition. For backward compatible reasons, if of length one, then it's equivalent to specifying `fraction = c(reference = 1/2, test = fraction)`.
`warn`	If `TRUE`, a warning is produced if the partitions produced are not of equal size.

A list of two disjoint random non-overlapping partitions where each element holds indices in {1, 2, ..., n}. The first element holds the 'reference' partition and the second the 'test' partition. As an example, if fraction[1] == 1/2, then the reference partition P_0.5 holds n/2 indices and the test partition holds indices in {1, 2, ..., n} \ P_0.5 where the size of the partitions corresponds to the sizes specified by fraction[2].
