174  * This function is two-fold:
175  * 1.) Start reading file, determine the file format:
176  * Input parameters:
177  * rPath - file path
178  * rFormatExtension - content matter
179  * bTest - set false
180  * Output parameters:
181  * Return value - true if success
182  * rFormatExtension - on success: normal file extension in capitals
183  * 2.) Start reading file, verify file format
184  * Input parameters:
185  * rPath - file path
186  * rFormatExtension - normal file extension in capitals
187  * bTest - set true
188  * Output parameters:
189  * Return value - false, if cannot verify the file type
190  * passed to the function
191  * true, when the format is PROBABLY verified or
192  * WHEN THE FORMAT IS NOT KNOWN!
