Omar Zrien cd5765559a Last feature addition for CANTalon java/C++ user-facing API.
- CANJaguar also touched up to report it can't do the new control mode (just like with follower).
- New third optional param for talon c'tor to speed up enable control frame.
- The pulse width routines have been moved to where the script generator puts them.  No actual changes there but should help Peter integrate the latest code generator.

Last feature additions for TalonSRX HAL for FRC2015-FRC-2016 season.

-HAL driver uses control_5 frame if firmware supports it.  This allows teams to see/confirm control settings taking effect before enabling the robot.
  For example selecting the sensor type and going to web-dash to check sensor values now works without having to enable the robot.
-Motion profile HAL routines added.  Tested on Single-Speed Double reduction (with slave Talon too).
-Start moving ctre frame defs into a new common header (better then shoving a bunch of struct defs at top of module).
-New child class in CANTalonSRX for buffering motion profile points.  Not sure it would be best to leave it as is or make another module.  It's trivial now so I thought that was acceptable, (in future it will likely possess compression strategies => no longer trivial).

/**
* @brief CAN TALON SRX driver.
*
* The TALON SRX is designed to instrument all runtime signals periodically. The default periods are chosen to support 16 TALONs
* with 10ms update rate for control (throttle or setpoint). However these can be overridden with SetStatusFrameRate. @see SetStatusFrameRate
* The getters for these unsolicited signals are auto generated at the bottom of this module.
*
* Likewise most control signals are sent periodically using the fire-and-forget CAN API.
* The setters for these unsolicited signals are auto generated at the bottom of this module.
*
* Signals that are not available in an unsolicited fashion are the Close Loop gains.
* For teams that have a single profile for their TALON close loop they can use either the webpage to configure their TALONs once
* or set the PIDF,Izone,CloseLoopRampRate,etc... once in the robot application. These parameters are saved to flash so once they are
* loaded in the TALON, they will persist through power cycles and mode changes.
*
* For teams that have one or two profiles to switch between, they can use the same strategy since there are two slots to choose from
* and the ProfileSlotSelect is periodically sent in the 10 ms control frame.
*
* For teams that require changing gains frequently, they can use the soliciting API to get and set those parameters. Most likely
* they will only need to set them in a periodic fashion as a function of what motion the application is attempting.
* If this API is used, be mindful of the CAN utilization reported in the driver station.
*
* Encoder position is measured in encoder edges. Every edge is counted (similar to roboRIO 4X mode).
* Analog position is 10 bits, meaning 1024 ticks per rotation (0V => 3.3V).
* Use SetFeedbackDeviceSelect to select which sensor type you need. Once you do that you can use GetSensorPosition()
* and GetSensorVelocity(). These signals are updated on CANBus every 20ms (by default).
* If a relative sensor is selected, you can zero (or change the current value) using SetSensorPosition.
*
* Analog Input and quadrature position (and velocity) are also explicitly reported in GetEncPosition, GetEncVel, GetAnalogInWithOv, GetAnalogInVel.
* These signals are available all the time, regardless of what sensor is selected at a rate of 100ms. This allows easy instrumentation
* for "in the pits" checking of all sensors regardless of modeselect. The 100ms rate is overridable for teams who want to acquire sensor
* data for processing, not just instrumentation. Or just select the sensor using SetFeedbackDeviceSelect to get it at 20ms.
*
* Velocity is in position ticks / 100ms.
*
* All output units are in respect to duty cycle (throttle) which is -1023(full reverse) to +1023 (full forward).
* This includes demand (which specifies duty cycle when in duty cycle mode) and rampRamp, which is in throttle units per 10ms (if nonzero).
*
* Pos and velocity close loops are calc'd as
* err = target - posOrVel.
* iErr += err;
* if( (IZone!=0) and abs(err) > IZone)
* ClearIaccum()
* output = P X err + I X iErr + D X dErr + F X target
* dErr = err - lastErr
* P, I,and D gains are always positive. F can be negative.
* Motor direction can be reversed using SetRevMotDuringCloseLoopEn if sensor and motor are out of phase.
* Similarly feedback sensor can also be reversed (multiplied by -1) if you prefer the sensor to be inverted.
*
* P gain is specified in throttle per error tick. For example, a value of 102 is ~9.9% (which is 102/1023) throttle per 1
* ADC unit(10bit) or 1 quadrature encoder edge depending on selected sensor.
*
* I gain is specified in throttle per integrated error. For example, a value of 10 equates to ~0.99% (which is 10/1023)
* for each accumulated ADC unit(10bit) or 1 quadrature encoder edge depending on selected sensor.
* Close loop and integral accumulator runs every 1ms.
*
* D gain is specified in throttle per derivative error. For example a value of 102 equates to ~9.9% (which is 102/1023)
* per change of 1 unit (ADC or encoder) per ms.
*
* I Zone is specified in the same units as sensor position (ADC units or quadrature edges). If pos/vel error is outside of
* this value, the integrated error will auto-clear...
* if( (IZone!=0) and abs(err) > IZone)
* ClearIaccum()
* ...this is very useful in preventing integral windup and is highly recommended if using full PID to keep stability low.
*
* CloseLoopRampRate is in throttle units per 1ms. Set to zero to disable ramping.
* Works the same as RampThrottle but only is in effect when a close loop mode and profile slot is selected.
*
* auto generated using spreadsheet and WpiClassGen.csproj
