 Passing both number and child_of parameters to get_pages will produce
 nonsensical results.

 Within the function number is used first to limit the number of results,
 then child_of is used to establish results within a certain hierarchical
 scope.

 So with a structure of:

 Parent 1
 Parent 2
 Parent 3
    Child 1
    Child 2
    Child 3

 passing a number=2 and child_of=(parent 3 id) will not give the expected
 output. In this case, the result will first be limited to only include:

 Parent 1
 Parent 2

 so the child_of will be ignored. To produce a more logical result,
 child_of should be evaluated first, then number should be evaluated to
 limit the result set.
