31 * @class SRC
32 *
33 * SRC stands for System Reference Code.
34 *
35 * This class represents the SRC sections in the PEL, of which there are 2:
36 * primary SRC and secondary SRC. These are the same structurally, the
37 * difference is that the primary SRC must be the 3rd section in the PEL if
38 * present and there is only one of them, and the secondary SRC sections are
39 * optional and there can be more than one (by definition, for there to be a
40 * secondary SRC, a primary SRC must also exist).
41 *
42 * This section consists of:
43 * - An 8B header (Has the version, flags, hexdata word count, and size fields)
44 * - 8 4B words of hex data
45 * - An ASCII character string
46 * - An optional subsection for Callouts
