Summarises the cross-over designs available via the function seq_clatworthy_williams.

1	summary_seq_clatworthy_williams(D, J, K, summary = T)

`D`	The number of treatments. If specified, must be a single `numeric` integer greater than or equal to two. Defaults to missing, which means no subsetting of the available designs is performed based on the number of treatments.
`J`	The number of periods. If specified, must be a `numeric` vector, containing integer values greater than or equal to two. Defaults to missing, which means no subsetting of the available designs is performed based on the number of periods.
`K`	The number of sequences. If specified, must be a `numeric` vector, containing integer values greater than or equal to two. Defaults to missing, which means no subsetting of the available designs is performed based on the number of sequences.
`summary`	A `logical` variable indicating whether a summary of the function's progress should be printed to the console. Defaults to `T`.

summary_seq_clatworthy_williams() supports the determination of which designs are available from seq_clatworthy_williams. Precisely, values for the number of treatments (see D), periods (see J), and sequences (see K) desired in the design is specified. Then, the function returns which compatible designs are supported by seq_clatworthy_williams.

A tibble containing the available designs from seq_clatworthy_williams for the chosen values of D, J, and K.
