====== SetHash/GetHash ======

The SetHash function creates a hashmap of a set of selected elements. \\ 
The key is the element specified in the second parameter. \\\ 
The GetHash function then returns the corresponding element from the above selection for a given hashmap + key.

==== Syntax: ====

<code>SetHash('selection', 'Key', 'Name of the hashmap')</code>
<code>GetHash('Name of the hashmap', 'Key')</code>

==== Sample: ====

In this example, a hashmap is created using a series of **SG_33 nodes**, with the **/LIN/@DE_1028** attributes serving as the key for each node. GetHash returns the **/SG_33** node with the **@DE_1028** attribute value 18089.
<code>SetHash(//SG_33,'LIN/@DE_1082','hash1')</code>
<code>GetHash('hash1','18089')</code>
