+FILECanonicalizePath
+    Removes all instances of '/./', '/../' and '//' from an absolute path. 
+    
+Parameters:
+    LPSTR lpUnixPath : absolute path to modify, in Unix format
+
+(no return value)                                             
+ 
+Notes :
+-behavior is undefined if path is not absolute
+-the order of steps *is* important: /one/./../two would give /one/two 
+ instead of /two if step 3 was done before step 2
+-reason for this function is that GetFullPathName can't use realpath(), since 
+ realpath() requires the given path to be valid and GetFullPathName does not.
