//+------------------------------------------------------------------+
//| Function..: StringArraySort |
//| Based on..: BenchStringArraySort.mq4 by http://www.MetaQuotes.net|
//| and modified to handle two dimensional arrays and |
//| descend mode. |
//| Parameters: A - Name of the string array. |
//| iStart - Start row, the default value is row zero if |
//| the parameter is omitted. |
//| iCount - Count of rows to be sorted, defaults to the |
//| whole array if the parameter is not passed |
//| or passed as 0 (zero). |
//| iDir - Array sorting direction. It can be either |
//| of the following values: |
//| MODE_ASCEND (1) - sort ascending A to Z, |
//| MODE_DESCEND (2) - sort descending Z to A. |
//| Purpose...: Sort the two dimensional array by the first column. |
//| Returns...: The sorted string array passed by reference. |
//| Sample....: string A[2][2]={"GBPUSD","500","EURUSD","600"}; |
//| StringArraySort(A); |
//| StringArrayWrite(A); |
