+    CAUTION: this is version will add an additional layer in the folder
+    structure in order to seperate input and output file types:
+        input:
+            htc
+                DLCs
+            data
+            control
+        output:
+            res
+            logfiles
+
+    Function which updates HtcMaster.tags and returns an HtcMaster object
+
+    Only use lower case characters for case_id since a hawc2 result and
+    logfile are always in lower case characters.
+
+    BE CAREFULL: if you change a master tag that is used to dynamically
+    calculate an other tag, that change will be propageted over all cases,
+    for example:
+    master.tags['tag1'] *= master.tags[tag2]*master.tags[tag3']
+    it will accumlate over each new case. After 20 cases
+    master.tags['tag1'] = (master.tags[tag2]*master.tags[tag3'])^20
+    which is not wanted, you should do
+    master.tags['tag1'] = tag1_base*master.tags[tag2]*master.tags[tag3']
+
+    This example is based on reading the default DLC spreadsheets, and is
+    already included in the dlcdefs.excel_stabcon
