Constructs a string based on parameters, and uses that as the content of a custom pspec file.
Parameters effect the volatility of the symbol "PORTF". 
The pspec file is read by the SleighLanguage object which tracks volatile addresses.
@param symbolVolatile Nullable boolean value that specifies the symbol PORTF volatility setting.
@param symbolSize Nullable integer value specifying the symbol PORTF size in bytes.
@param memoryVolatile Nullable boolean value that specifies the volatility setting of the 
			memory location that includes PORTF.
@param reverseOrder boolean, reverseOrder refers to the order that 'volatile' and 
			'default_symbols' elements appear in the pspec file.
@throws Exception if an error occurred
