• Added definitions for types found in cstdint. Added types FixedWidthIntegralType, MinimumWidthIntegralType, FastestMinimumWidthIntegralType, and MaximumWidthIntegralType to describe types such as int8_t, int_least8_t, int_fast8_t, and intmax_t respectively.
• Changed definition of Intmax_t and Uintmax_t to be part of the new type structure.
• Added a type FixedWidthEnumType which describes enums based on a fixed-width integer type. For instance, enum e: uint8_t = { a, b };.
