(SQL Server) Firebase PUT - Writing Data

Demonstrates how to PUT new data to a Firebase JSON database. The data used in this example is at Chilkat Firebase Pigs Database, and is shown here:

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

    --  This example requires the Chilkat API to have been previously unlocked.
    --  See Global Unlock Sample for sample code.

    --  This example assumes a JWT authentication token, if required, has been previously obtained.
    --  See Get Firebase Access Token from JSON Service Account Private Key for sample code.

    --  Load the previously obtained Firebase access token into a string.

    --  Note: In many of the Chilkat examples, you may notice strange ways
    --  of doing something that should be simpler and shorter.  For example,
    --  building the path (above) could've been written differently,
    --  with some simple string concatenation.
    -- 
    --  The reason is that the Chilkat examples are written in a
    --  proprietary "example code" scripting language,
    --  and then automatically generated to each of the different programming
    --  languages you see on example-code.com.  The code generation is
    --  limited in what it can do.  For example, string concatentation
    --  is not yet a feature of the "example code" scripting language (as of May 2016),
    --  and therefore you won't see the use of a programming language's string
    --  concatentation operators in any example.
