Check that a variable is an Array, if not turn it into one
If a symbol is given as a second option, assume the sym is the name of a instance variable, send the instance_variable to value of its new attr (Array)
NOTE: Should not give sym as option if defining the attribute method for the same name attribute, will cause infinite loop. Mostly this option is for use
within initialize method
