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