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.
