Generated PER Decode Functions

---

PER encode/decode functions are generated when the `-per' switch is specified on the command line. For each ASN.1 production defined in the ASN.1 source file, a C PER decode function is generated. This function will parse the data contents from a PER-encoded ASN.1 message and populate a variable of the corresponding type with the data.

If C++ code generation is specified, a control class is generated that contains a Decode method that wraps this function. This function is invoked through the class interface to encode an ASN.1 message into the variable referenced in the msgData component of the class.
