/**
 * Formats simple patterns like "{1} was born in {0}".
 * Minimal subset of MessageFormat; fast, simple, minimal dependencies.
 * Supports only numbered arguments with no type nor style parameters,
 * and formats only string values.
 * Quoting via ASCII apostrophe compatible with ICU MessageFormat default behavior.
 *
 * Factory methods set error codes for syntax errors
 * and for too few or too many arguments/placeholders.
 *
 * SimpleFormatter objects are thread-safe except for assignment and applying new patterns.
 *
 * Example:
 * <pre>
 * UErrorCode errorCode = U_ZERO_ERROR;
 * SimpleFormatter fmt("{1} '{born}' in {0}", errorCode);
 * UnicodeString result;
 *
 * // Output: "paul {born} in england"
 * fmt.format("england", "paul", result, errorCode);
 * </pre>
