;  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.
