New Version of Recognition Method

1. Improvement of recognition algorithm
2. Significant improvement in language processing function through language dictionary
3. Improved discrimination performance of voiced and semi-voiced sounds
4. Automatic detection of separations caused by recognition of semantic radicals
5. Automatic processing of bracket matching
6. Possibility to add underline processing (default: no underline processing)

// Paragraph recognition
	int mrecognizecluster(unsigned long chartype1,unsigned long chartype2);
	Input:
	unsigned long chartype1; 		Character type filter 1
						CHAR_SET_ALL, CHAR_SET_ENGLISH, CHAR_SET_NUMBERALL
						and combinations of these
	unsigned long chartype2;			Character type filter 2
						0 or CHAR_SET_ASCII specified
						Characters not specified in chartype1 are not included in the result
						If CHAR_SET_ASCII is specified in chartype2, recognition is further limited to ASCII characters
						Recognition rate and speed also increase
	Return:
	0..................Normal completion
	MEMORY_SHORTAGE...Memory shortage

// Adding underline processing
	void msetunderlineflag(int flag = 1);
	Input:
	int flag;				0 or 1 (1 enables underline processing)
