#' fo_to_char
#'
#' Converts a formula to character representaion.
#'
#' `fo_to_char`` is a function provided for use to interface with
#' `as.character.formula`. If 'biodatacoreUtils' is loaded, then `as.character`
#' should automatically find the `.formula` method. `deparse_to_str` is the
#' underlying function that does the conversion.

#' @param x formula
#' @param ... arguments passed to and from other methods.
