lowertri_constraint_matrix: Lower Triangular Factor Constraints
In jrnold/flatter: Flattened arrays

Create lower-triangular constraints as used for the loadings matrix in confirmatory factor analysis.

1	lowertri_constraint_matrix(n, factors = 1, ones = TRUE)

`n`	Number of variables
`factors`	Number of factors
`ones`	If `TRUE`, then the diagonal is equal to 1, if `FALSE` the diagonal is set to `Inf` (positive).

Matrix with n rows and factors columns, with 1's or Inf on the diagonal, NA below the diagonal, and 0's above the diagonal.
