Compare the contents of the descriptor with another one passed as a parameter. Checks if the
obj passed is an instance of ModifyableTableDescriptor, if yes then the contents of the
descriptors are compared.
@param obj The object to compare
@return true if the contents of the the two descriptors exactly match
