var TinyintAsBool bool

TinyintAsBool is a global that is set from main.go if a user specifies this flag when generating. This flag only applies to MySQL so we're using a global instead, to avoid breaking the interface. If TinyintAsBool is true then tinyint(1) will be mapped in your generated structs to bool opposed to int8.
