|   The function "datadecode" decodes the tracker words.
*   
|   Tracker words are of three types:
*   - ADC data 
|   - strip address
*   - end of ladder
|   
*   The function returns a struct variable (trkword) 
|   that contains two quantities, type and decode, which are assigned 
*   the following values:
|   
*   type                     decode              
|   ----------------------------------------------------
*   -1     error             0          
|    0     data              0-4095   ADC values
*    1     address           0-1023   strip address (relative to ladder)
|    2     end-of-ladder     1,2,3    ladder number     (compressed acq mode)      
*                            4,5,6    ladder number + 3 (full acq mode)
