34* @name Quantize
35*
36* This function quantizes the mentioned quantity to nearest level.
37*
38* @param p
39* Should be a quantity in percentage.
40*
41* @return Nearest quantized level, can be directly used as array index based on context.
42*
43 @remarks This function uses centred/symmetric logic for quantization.
44 For the case of lvl = 4, You will get following integer levels if given (p) value falls in between the range partitions:
45 0 <= p < 12.5 : returns 0; (corresponding to 0% centre)
46 12.5 <= p < 37.5 : returns 1; (corresponding to 25% centre)
47 37.5 <= p < 62.5 : returns 2; (corresponding to 50% centre)
48 62.5 <= p < 87.5 : returns 3; (corresponding to 75% centre)
49 87.5 <= p <= 100 : returns 4; (corresponding to 100% centre)
