04/05/2012 New version of API for IFBeam data.

The low level function(s) are now isolated from the user. 
Two higher level functions introduced: getBandle4t and getBandle4tt, they allow
to get the data for the bundle either for given time or for the time range.
They both return the pointer to the NULL terminated data record array, which has to be 
destroyed after use.

The sequence of operations may look like this:


#include "ifbeam_csv.h"
#include "ifbeam_decode.h"
    .........
    DataRec **dataRecs = getBandle4t("url_for_the_service", "bundle_name", time0);              // Get the data for bundle

    DataRec **dr = dataRecs;                            // Set moving pointer to the first record

    for ( ; *dr!=NULL; dr++) {                          // Walk through record array
        ExperimentData *eData = decodeMBED1x(*dr);      // Try to decode MBED10/MBED12 record
        if (eData) {                                    // If we get a decoded record do something with it...
            ........
        }
    }
    destroyDataRecs(dataRecs);  // Free allocated memory
    .........
