+.DESCRIPTION
+    Securely allows to sort arrays for containing objects like hashtables,
+    which is not simply done by using Sort-Object, but requires custom expressions
+    (ScriptBlocks) to deal with the sorting.
+
+    Icinga for Windows does not allow ScriptBlocks inside external modules while using
+    JEA profiles. Sorting expressions are ScriptBlocks which are not allowed in JEA
+    context. To ensure module developers can still sort objects from inside arrays,
+    this function allows to parse the InputObject as array and adding the name of the
+    member which should be sorted. In addition it allows configuration if the result
+    should be sorted Descending or Ascending (default)
+.PARAMETER InputObject
+    An array containing all our objects. Defined as Pipeline input
+.PARAMETER MemberName
+    The member name from within your array objects to sort the result for
+.PARAMETER Descending
+    Set to sort the output result Descending
+.EXAMPLE
+    PS> ConvertTo-IcingaSecureSortedArray -InputObject $MyArray -MemberName 'CreationTime';
+.EXAMPLE
+    PS> ConvertTo-IcingaSecureSortedArray -InputObject $MyArray -MemberName 'CreationTime' -Descending;
+.EXAMPLE
+    PS> $MyArray | ConvertTo-IcingaSecureSortedArray -MemberName 'CreationTime' -Descending;
