#Attribute Dictionarizer

#Allows user to assign the class "objectAttr" to a variable
#This class has 3 methods, create, change value, and show value
#When you change a value using objectAttr.chVal() you must pass an argument in the form (Attribute Name,New Attribute Value)

#imports Maya and MEL modules
