Functions
MX_CORE_API bool	targetStringsMatch (const string &target1, const string &target2)
	Given two target strings, each containing a string array of target names, return true if they have any targets in common.
MX_CORE_API string	prettyPrint (ConstElementPtr elem)
	Pretty print the given element tree, calling asString recursively on each element in depth-first order.

targetStringsMatch()

MX_CORE_API bool targetStringsMatch	(	const string &	target1,
		const string &	target2 )

Given two target strings, each containing a string array of target names, return true if they have any targets in common.

An empty target string matches all targets.
