Represents an XML Instruction; IE, <? … ?> TODO: Add parent arg (3rd arg) to constructor
target is the “name” of the Instruction; IE, the “tag” in <?tag …?> content is everything else.
target is the “name” of the Instruction; IE, the “tag” in <?tag …?> content is everything else.
Constructs a new Instruction @param target can be one of a number of things. If String, then the target of this instruction is set to this. If an Instruction, then the Instruction is shallowly cloned (target and content are copied). If a Source, then the source is scanned and parsed for an Instruction declaration. @param content Must be either a String, or a Parent. Can only be a Parent if the target argument is a Source. Otherwise, this String is set as the content of this instruction.

@return true if other is an Instruction, and the content and target of the other matches the target and content of this object.
