NAME
RecordInstruction - Parse a line from the the file to determine the the type of
instruction and record all important values.
SYNOPSIS
Instruction::InstructionType Instruction::RecordInstruction(string &a_buff);
a_buff - passed by reference, the line from the file to be parsed.
DESCRIPTION
First parse out all comments from the line. Then determine whether or not
a label exists on the line. Perform some error checking and set all important values including
label, opcode, and operand. Then determine if the opcode is an assembly instruction or
machine language instruction. If assembly check to see if it is an end command.
RETURNS
InstructionType ST_Comment if after parsing the line for comments, it is blank.
ST_End if the opcode is determined to be "END".
ST_AssemblerInstr if it is an assembly instruction with no associated numeric opcode.
Otherwise it is a ST_MachineLanguage.
