+TBars class - includes all series for common data used in indicators and other calculations.
+    Has a bit limited overloading and casting (compared to TSeries)
+    Includes Select(int) method to simplify choosing the most optimal data source for indicators
+    Includes the most basic pricing calcs: HL2, OC2, OHL3, HLC3, OHLC4, HLCC4 
+        (it is 'cheaper' to calculate them once during data capture than each time during data analysis)
