Namespaces
namespace	cadabra
	Functions to handle the exchange properties of two or more symbols in a product.

Functions
void	cadabra::do_list (const Ex &tr, Ex::iterator it, std::function< bool(Ex::iterator)> f)
	Apply a function on every element of a list, or if the iterator 'it' does not point to a list, only on that single element.
int	cadabra::list_size (const Ex &tr, Ex::iterator it)
	For lists as defined above for 'do_list', return their size (in case you really need to know the size before iterating over the elements).
Ex::iterator	cadabra::find_in_subtree (const Ex &tr, Ex::iterator it, std::function< bool(Ex::iterator)> f, bool including_head=true)
	Returns an iterator to the first element for which 'f' returns 'true', or 'tr.end()'.
Ex::iterator	cadabra::find_in_list (const Ex &tr, Ex::iterator it, std::function< Ex::iterator(Ex::iterator)> f)
	Returns an iterator to the first element for which 'f' does not return tr.end().
Ex	cadabra::make_list (Ex el)
	Ensure that the tree is a list, even if it contains only a single element.
