Data
 Data to calculate Intraclass Correlation Coefficient ρ from clusters of n, mean, and SD is in 3 columns
     - Each calculation is for a single study
     - Each row the data from a cluster
     - Col 1 is sample size of cluster
     - Col 2 is the mean of cluster
     - Col 3 is the Standard Deviation of cluster
Data to calculate Intraclass Correlation Coefficient ρ from clusters of from clusters of binomial data is in 2 columns
     - Each calculation is for a single study
     - Each row the data from a cluster
     - Col 1 is group designation and should be 1 or 2
     - Col 2 is the number of positives in the cluster
     - Col 3 is the number of negatives in the cluster
Data to calculate sample size from Intraclass Correlation Coefficient ρ and number of cluster is in 3 columns
     - Each calculation is for multiple studies
     - Each row the data for a study
     - Col 1 is sample size per group according to individual randomisztion
     - Col 2 is Intraclass Correlation Coefficient ρ
     - Col 3 is number of clusters proposed
