Reads a file (identified by inputFilePath), one character at a time.
* Products start with
and end with
as describeed above.
* Reviews start with and end with as describeed above.
* Any text not inside of one of these tags should be ignored.
*
* You may use only CharacterFromFileReader to read characters from the
* input file.
*
* In order to simplify the code writing experience, it is recommended
* that you use a switch statement where the case would be the state.
* This way, you only need to worry about what happens when you are at
* that state. You should, however, fully understand the state diagram
* as a whole and in parts, as you will be required to complete this
* assignment next week at the beginning of lab.
*
* @param String
* inputPath the path on the local filesystem to the input file
* @returns a HashMap containing the product->list of reviews mappings.
