uppertri_mult_diag

nimbleFunction needed when fitting correlated random effects.
Generates upper triangular Cholesky factor of covariance matrix ("U" in code)
from upper triangular Cholesky factor of correlation matrix ("Ustar" in code)
and vector of standard deviations. Taken from the NIMBLE manual, 
section 5.2.4.1.2 (LKJ Distribution for Correlation Matrices).

Macros to generate 'nimble' code from a concise syntax. Included are macros for generating linear modeling code using a formula-based syntax and for building for() loops. For more details review the 'nimble' manual: <https://r-nimble.org/html_manual/cha-writing-models.html#subsec:macros>.
