class	ON_SubDHash
	ON_SubDHash provides a simple way to save a SubD's vertex, edge, and face SHA1 hashes. Typically it is used when a calculation needs to know if the current SubD has is geometrically identical to a previous SubD. When speed is not important, comparing the current value of ON_SubD::GeometryHash() to a previously save value of ON_SubD::GeometryHash() is functionally identical but typically much slower when the SubDs are different.

	ON_UnicodeShortCodePoint is a tool to use when working with Unicode code points with values &lt=0xFFFF. Note that valid Unicode code point values can be as large as 0x10FFFD. (0x10FFFE and 0x10FFFF are specified as &ltnot a character&gt by the Unicode Standard code chart https://www.unicode.org/charts/PDF/U10FF80.pdf) This class is used when converting between Unicode and BIG5 encodings and in other settings where Unicode code points &gt 0xFFFF are not encountered and the 2 byte size of ON_UnicodeShortCodePoint appreciably more efficient that a 4 byte size of an unsigned int.
