Created serial module, variables, and prints

Created data variables and begin mapping of data variables to correct
units.
Serial module started.
Beginning prints of serial data.
Created my_map function and declaration

Adapting map function to output a double, as +/- 1.5 g sensitivity will
be used on the accelerometer.
Casting variables in grav's my_map

All variables should be input as floats
Mapping raw data from Gyro

Using map() instead of my_map because output must be in range -500 dps
to +500 dps (degrees per second).
Formatting added for readings chart
Formatting error

Serial.println because of chart index
Including Stepper Motor

Stepper Motor will be used for Wheels
Stepper Motor intialized

STEPS const must be declared later...
Fix formatting output for gyro - begin motorSpeed

motorSpeed can be changed during loop()
according to size of gyro output.
Created steps variable, map dps for motorSpeed

Calculating appropriate motorSpeed between 5-->60 RPM, mapped over dps.
