// reformat (TARGETSTRING, STRING, INTEGER, STRING, INTEGER ... )
//
// Handy function for arbitrarily inserting formatting characters
// or delimiters of various kinds within TARGETSTRING.
//
// reformat takes one named argument, a string s, and any number
// of other arguments. The other arguments must be integers or
// strings. These other arguments specify how string s is to be
// reformatted and how and where other strings are to be inserted
// into it.
//
// reformat processes the other arguments in order one by one.
// * If the argument is an integer, reformat appends that number
// of sequential characters from s to the resultString.
// * If the argument is a string, reformat appends the string
// to the resultString.
//
// NOTE: The first argument after TARGETSTRING must be a string.
// (It can be empty.) The second argument must be an integer.
// Thereafter, integers and strings must alternate. This is to
// provide backward compatibility to Navigator 2.0.2 JavaScript
// by avoiding use of the typeof operator.
//
// It is the caller's responsibility to make sure that we do not
// try to copy more characters from s than s.length.
//
// EXAMPLES:
//
// * To reformat a 10-digit U.S. phone number from "1234567890"
// to "(123) 456-7890" make this function call:
// reformat("1234567890", "(", 3, ") ", 3, "-", 4)
//
// * To reformat a 9-digit U.S. Social Security number from
// "123456789" to "123-45-6789" make this function call:
// reformat("123456789", "", 3, "-", 2, "-", 4)
//
// HINT:
//
// If you have a string which is already delimited in one way
// (example: a phone number delimited with spaces as "123 456 7890")
// and you want to delimit it in another way using function reformat,
// call function stripCharsNotInBag to remove the unwanted
// characters, THEN call function reformat to delimit as desired.
//
// EXAMPLE:
//
// reformat (stripCharsNotInBag ("123 456 7890", digits),
// "(", 3, ") ", 3, "-", 4)
