Handling of Base64-encoded information

This Codeunit is my take on handling Base64 encoded-information in payloads of Webservices. The goal of the Codeunit is to be able to identify a Base64-string inside a variable which content is unknown and to store the content in a BLOB-field.

The Codeunit contains the following functions:

• isBase64(pVariant) -> This function is used to identify if a variable contains a Base64-encoded information
• TryToStoreVariantAsBLOB(pVariant, pTempBLOB) -> This function is stores the Base64-encoded information into a Blob-Field.
   
• RunExample() -> Have a look for this function if you want to understand the Codeunit
• LoadExampleData(UnknownValue1, UnknownValue2) -> This function is used to load example data for the "RunExample"-function
