The DataCollect object expands the number of data attribues that
 can be handled in a DataArithm object.

 The DataCollect has 24 data inputs, which values are stored in an array.
 By connecting the output of the DataCollect object to a Data input of a
 DataArithm object, it is possible to handle the array in the code of the
 DataArithm. This expands the number of data inputs to the DataArithm
 from ordinary 4 to 96, when all four data inputs are connected to DataCollect
 objects.

 Another advantage of DataCollect is that its sometimes convenient to have
 the values arranged in an array, for example to use in a for or
 while loop.

 MaxIndex should be assigned the number of used inputs in the DataCollect
 object.

 This is the code in a DataArithm which has a DataCollect object connected
 to the Da1 input.

     classdef Da1 DataCollect;
     int i;

     OA1 = 0;
     for ( i = 0; i < Da1->MaxIndex; i++)
       if ( ((pwr_sClass_Mtrl *)(Da1->DataP[i].Ptr))->Length > 10.0)
         OA1++;

 Data input

 Number of used inputs.

 Array that contains pointers to the the data input objects.

 Data output that can be connected to a DataArithm (or som other Data input).
