Updated for 32/64 bit architecture. Note that direct obj-c isa access is deprecated in the modern runtime. These warnings have not yet been resolved as there may be performance penalties on all arithmetic. However, the change may be necessary.
Replaced ->isa with object_getClass() to conform to requirements of the modern runtime. This will affect arithnetical efficiency but is necessary if a seg fault is to be avoided on tagged pointers.
Added warning flag -Wmissing-method-return-type and fixed resultant warnings: Method has no return type specified.
Added newline to end of heder to silence warnings generated from -Wall, Wextra when importing header into projects with tighter warnings.
Removed direct use of ->isa and replaced with object_getClass()
