// This class represents an XCOFF `Control Section`, more commonly referred to
// as a csect. A csect represents the smallest possible unit of data/code which
// will be relocated as a single block. A csect can either be:
// 1) Initialized: The Type will be XTY_SD, and the symbols inside the csect
//    will have a label definition representing their offset within the csect.
// 2) Uninitialized: The Type will be XTY_CM, it will contain a single symbol,
//    and may not contain label definitions.
// 3) An external reference providing a symbol table entry for a symbol
//    contained in another XCOFF object file. External reference csects are not
//    implemented yet.
