Arguments

class: A class names for the condition; message_condition(), warning_condition(), error_condition() will always use classes "message", "warning", "error", respectively.
message, ...: A character vector of message components; message is used for anything with a default message.
call: The call that generated the condition
package: Package name. Default will attempt to find the package by the calling environment, which must return a character value. This will also be passed to the package argument in new_condition()
