MRSS functions for designs with fixed blocks find number of clusters per block rather than number of blocks
shorter function names, e.g., mdes.cra3() <= mdes.cra3r3(), mdes.bira3() <= mdes.bira3r1() (still accommodates older function names)
added mod211 and mod212 functions (Dong, Kelcey, & Spybrook, 2021)
added power.med331() and power.med311() functions (Kelcey, Xie, Spybrook, & Dong, 2020)
added power.rep() and mdh.rep() functions (Hedges & Schauer, 2019)
added partially nested designs (Kelcey, Bai, & Xie, 2020; Lohr, Schochet, & Sanders, 2014)
added optional effect size variability argument to blocked designs

added moderation designs for two- and three-level cluster randomized trials
added mediation designs for two-level cluster randomized trials
fixed a bug in .error.handler(). We thank Dr. Thomas J. Leeper for bringing the bug to our attention and suggesting evaluating arguments before validation process
re-defined the argument rho to avoid confusion. We thank Dr. Benjamin Nagengast for bringing this issue to our attention

documented functions by designs
efficiency improvements, better error handling
removed constrained optimal sample allocation functions. See cosa package
simplified MRSS functions
fixed a bug in t1t2.error() plotting function. We thank Dr. Eric. C. Hedberg for bringing the bug to our attention.
