 options:
 compile time options:
  OgreNoneOption				no option
  OgreSingleLineOption			'^' -> '\A', '$' -> '\z', '\Z' -> '\z'
  OgreMultilineOption			'.' match with newline
  OgreIgnoreCaseOption			ignore case (case-insensitive)
  OgreExtendOption				extended pattern form
  OgreFindLongestOption			find longest match
  OgreFindNotEmptyOption		ignore empty match
  OgreNegateSingleLineOption	clear OgreSINGLELINEOption which is default on
								in OgrePOSIXxxxxSyntax, OgrePerlSyntax and OgreJavaSyntax.
  OgreDontCaptureGroupOption	named group only captured.  (/.../g)
  OgreCaptureGroupOption		named and no-named group captured. (/.../G)
  OgreDelimitByWhitespaceOption	delimit words by whitespace in OgreSimpleMatchingSyntax
  								@"AAA BBB CCC" <=> @"(AAA)|(BBB)|(CCC)"
  
 search time options:
  OgreNotBOLOption			string head(str) isn't considered as begin of line
  OgreNotEOLOption			string end (end) isn't considered as end of line
  OgreFindEmptyOption		allow empty match being next to not empty matchs
	e.g. 
	regex = [OGRegularExpression regularExpressionWithString:@"[a-z]*" options:compileOptions];
	NSLog(@"%@", [regex replaceAllMatchesInString:@"abc123def" withString:@"(\\0)" options:searchOptions]);

	compileOptions			searchOptions				replaced string
 1. OgreFindNotEmptyOption  OgreNoneOption				(abc)123(def)
							(or OgreFindEmptyOption)		
 2. OgreNoneOption			OgreNoneOption				(abc)1()2()3(def)
 3. OgreNoneOption			OgreFindEmptyOption			(abc)()1()2()3(def)()
