// reformatString(targetStr [, str1, int1, str2, int2, ... strN, intN])
//
// Handy function for arbitrarily inserting formatting characters
// or delimiters of various kinds within targetString.
//
// reformatString() takes one required string argument, targetStr,
// and 0-N optional string/integer-pair arguments. These optional
// arguments specify how targetStr is to be reformatted and how/where
// other strings are to be inserted in it.
//
// reformatString() processes the optional args in order one by one.
// * If the argument is an integer, reformatString() appends that number
//   of sequential characters from targetStr to the resultString.
// * If the argument is a string, reformatString() 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:
//   reformatString("1234567890", "(", 3, ")", 3, "-", 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 stripCharsNotInBag() or stripBlanks() to remove unwanted
// characters, THEN call function reformatString to delimit as desired.
//
// EXAMPLE:
//
// reformatString(stripCharsNotInBag ("123 456 7890", digits),
//           "(", 3, ") ", 3, "-", 4)
