** \brief Convenience node builders.
**
** These are convenience node builders for building AND, OR, PLUS,
** and MULT expressions.
**
** \todo These should be moved into theory code (say,
** src/theory/booleans/node_builders.h and
** src/theory/arith/node_builders.h), but for now they're here
** because their design requires CVC4::NodeBuilder to friend them.
**/
// TODO: add templatized NodeTemplate<ref_count> to all these inlines
// for 'const [T]Node&' arguments? Technically a lot of time is spent
// in the TNode conversion and copy constructor, but this should be
// optimized into a simple pointer copy (?)
// TODO: double-check this.
