Creating name for columns and rows of OFI matrix.

This function creates name for columns and rows of OFI matrix.

ofim_name(G, weight, Dim, lambda, model = "restricted", family = "constant",
skewness = "FALSE", param )

`G`	number of components.
`weight`	a vector of weight parameters (or mixing proportions).
`Dim`	dimension size.
`lambda`	a list of skewness matrices of `G` components.
`model`	it must be `"canonical"`, `"restricted"`, or `"unrestricted"`. By default `model = "restricted"`.
`family`	name of mixing distribution. By default `family = "constant"` that corresponds to the finite mixture of multivariate normal (or skew normal) distribution. Other candidates for family name are: "bs" (for Birnbaum-Saunders), "burriii" (for Burr type iii), "chisq" (for chi-square), "exp" (for exponential), "f" (for Fisher), "gamma" (for gamma), "gigaussian" (for generalized inverse-Gaussian), "igamma" (for inverse-gamma), "igaussian" (for inverse-Gaussian), "lindley" (for Lindley), "loglog" (for log-logistic), "lognorm" (for log-normal), "lomax" (for Lomax), "pstable" (for positive `\alpha`-stable), "ptstable" (for polynomially tilted `\alpha`-stable), "rayleigh" (for Rayleigh), and "weibull" (for Weibull).
`skewness`	logical statement. By default `skewness = "TRUE"` which means that a skewed model is fitted to each component (cluster). If `skewness = "FALSE"`, then a symmetric model is fitted to each component.
`param`	name of the elements of `\bold{\theta}` as the parameter vector of mixing distribution with density function `f_W(w; {\bold{\theta})}`.
