Improved Rowing Engine (#24)
* Update to accomodate the new RowingEngine

Update of the MovingFlankDetector to provide the values needed to determine the speeds at the beginning of the flank.

* Created the MovingAverager for RowingEngine 2.0

Added the MovingAverager to accomodate the RowingEngine 2.0

* Update to RowingEngine 2.0

Update based on the great theoretical work of Anu Dudhia and the practical experiences of Dave Venrooy.

* Added to explain RowingEngine 2.0 design

A rationale for explaining the RowingEngine 2.0 design, based on the great theoretical work of Anu Dudhia, and the practical work of Dave Venrooy and Marinus van Holst, as well as the great feedback from Lars Berning.

* Update to accomodate the new RowingEngine

Update to the rower settings to accommodate the new RowingEngine. Please note that the modifications need to be verified by the respective users.

* Modifications to the RX800 tests

Modifications to the RX800 to bring it in line with the Concept2 Power and distance measurements.

* BUGFIX: Prevent ghost-strokes at end of session

This change to isAccelerating prevents stroke-detection to detect a stroke when the currentDt "flatlines". This typically happens when the error correction kicks in when you quit rowing (and thus the rowerSettings.maximumTimeBetweenImpulses is exceeded). It is bad (flatlining isn't acceleration), and this ghost-stroke causes havoc in the GUI: all measurements are reset again to random values instead of the nice indicators normally used.

* Added defensive programming

In some rare cases not rounding led to a buffer overflow, so added defensive programming to prevent this.

* Update MovingFlankDetector.js

* Improved stroke detection algorithm accuracy

Improvement of the Stroke detection algorithm: when naturalDeceleration is specified in the settings, it will only consider something a Revocery when this level of deceleration is encountered for the FlankLength.

* Made the RowingEngine more stateful

Removed some bugs, added a lot of defensive programming and made the RowingEngine report the key statistics every impuls to create a more fluid experience on the monitor. To do this, the rowingEngine maintins and reports absolute values to rowingStatistics, instead of relative.

* Improved stroke detection algorithm accuracy

Improvement of the Stroke detection algorithm: when naturalDeceleration is specified in the settings, it will only consider something a Revocery when this level of deceleration is encountered for the FlankLength.

* Modification to fit new RowingEngine

* Addition of new parameters for stroke detection

Added new parameters for stroke detection and monitor fluidity

* Fixed missing bracket

* Updated to more fluid RowingStatistics

Moved the timer from a static timer to the raw measurements of the flywheel, and the distance more frequently updated, to keep all data consistent. Also made the GUI-updates more fluid, responsive and dependent on settings: this more fluid GUI update mechanism is dependent on the screenUpdateInterval setting and moving averager dependent on a setting (numOfPhasesForAveragingScreenData)

* Made all monitor updates consistent

* Accommodate more frequent update of the monitors

Update to accommodate the more frequent updates, and to accommodate the reset for the RowingEngine

* improves some testcases, fixes some minor code styling and duplicate definitions

* Fixed a comment about dragfactor

* Added parameters for the new RowingStatistics.js

Added screenUpdateInterval, numOfPhasesForAveragingScreenData and maxCycleTimeBeforePause as config parameters to remove statically determined parameters in RowingStatistics.js

* Added RX800 as second testbed

* fixes some problems that caused the engine to crash

* uses non sanitized durations for now

* updates some settings, fixes some typos

* wires the correct timer configuration, fixes a problem where SPM would not reset to 0

* fixes a crash problem in workout recorder, fixes fallback value for strokeTime

* relaxes constraint on stroke time

* updates some explanatory text, updates some rower parameters

refactores FlankDetector, extracts some flank settings
* Improvement of the MovingflankDetector

Simplified the call of the moving flank detector, making it dependent on the settings

* Update MovingFlankDetector.js

Cleaned up the call to the MovingFlankDetector

* Added heartrate data to TCX

* Added parameters for the flankdetector

Added parameters for the flankdetector (flankLength and numberOfErrorsAllowed)

* Gave the RX800 some room as the settings haven't stabilised yet (and I think the recording is with a different damper setting than the source tree)

implements better flank detection, adds spreadsheet for analysis
Added the flankdetector, to reliably detect an acceleration or deceleration of the flywheel
Added extra metrics for the creation of TCX-files
Added extra metrics (speed in m/s and cadence) to allow future export of this data to Garmin TCX files, which everybody seems to love.
I increased the priority of the GPIO-service, as I noticed that much of the measurement noise originates from delayed read-outs of the GPIO.
An Excel tool to "play" with the settings of a rower, to adjust the settings found in the rowerprofiles.js
Adds test and data for RX800 rower
Lightweight version of Excel file
