ergm-errors: Sensible error and warning messages by ergm initializers

Description

These functions use traceback and pattern matching to find which ergm initializer caused the problem, and prepend this information to the specified message. They are not meant to be used by end-users, but may be useful to developers.

Usage

ergm_Init_abort(..., default.loc = NULL, call = NULL)
ergm_Init_stop(..., call. = FALSE, default.loc = NULL)
ergm_Init_warn(..., default.loc = NULL)
ergm_Init_warning(..., call. = FALSE, default.loc = NULL)
ergm_Init_inform(..., default.loc = NULL)
ergm_Init_message(..., default.loc = NULL)
ergm_Init_try(expr)

Arguments
