+/**
+ *  TRP105F_Spline.h,.cpp
+ *
+ *  -   This library is for provide a distance from TRP105F, proximity sensor,
+ *  to whatever reflect the flash.
+ *  -   Deistance is derived from a voltage signal of TRP105F.
+ *  -   An object of TRPFS class has an array of sets of
+ *  distance(16 bit-value) and voltage(16bit-value) at the distance.
+ *  -   The range of distances that an array has in sets is [0:1024] by 1.
+ *  -   an array is derived from a spline curve model.
+ *  -   In order to derive spline curve, some value sets should be got
+ *  at the first calibration.
+ *
+ *  LOG:
+ *  ver.1   2015/10/19 - 2015/10/22
+ *  ver.2   2015/10/22 -
+ *      Distance data type has become unsigned short from int.
+ *      Distance data range : [2:20] by 1 -> [0:1024] by 1.
+ *  ver.2.1 2016/02.12 -
+ *      Distance data range : [0:1024] -> [0:256].

+////    At calibration, at sampling data, first the class send '>' via seral com, 
+////  after which You can send distancedata [2,20][mm]. Then the class measure
+////  the voltage data for 1 sec.
+////    Above procedure is looped for the number you input in the constructor.
+////------------------------------------------
+////    (when TRP105FS object is made)
+////    >               (< you can input distance data after this signal('>' <=> 0x3e)
+////    >1              (< in this version, distance data is limited[2,20] integer.
+////    >14[CR or LF]   (< you can continue to input unless input ERNTER. But if you set [SYSTEM] on constructor you can input it only once. (use this in GUI)
+////    >14             (< then voltage mesuring begins.
+////                    (< after mesuring voltage, CR or LF signal is sent, which means tt is started a new line if console.
+////    >               (< when you shoud input more data, ':'signal is sent again.
