small improvement on the cricital sections : now copying the values into safe variables once every loop, added debug flags, now storing the injection start point in flash for resume, fixed a bug where slow injection speed could overflow the OCR1 register

Big rush before presenting the prototype v2 : added some ui details and buzzer cases, reworked the motor state machine to integrate the over pressure alarm, tweeked the values to fit the new prototype, added debug options

Corrected LCD connector alignment.
Widened LCD window for more margin.

We now have realistic time and volume calculations, tuned the Syringe list values after a series of tests, Added a STOP state

LCD positioning and cutout done.
Buttons positioning done.
MB connecteur positioning done.

Created symbol + footprint for tactile switches.
Created netlist.

The injection speed is now tunable during injection, the injection speed and remaining time alarm variables are now updated only after user confirmation

Fixed some menus timeouts, increased the menu timeout for slow users, inverted the green LED mode to fit the hospital standards, now saving the motor step and sensor position to provide a mmore accurate resume solution

Added the feedback sensor code : the motor movement is now checked by the external sensor, added the bases of the error management system and automatic motion functions

Huge rush before presenting the product : switched all the UI to fit a 20x4 chars LCD, Added a disclaimer, Added the BOLUS feature requested by doctors

Worked on feedbacks from lo2, now using MEMORY_XXX_MSB and MEMORY_XXX_LSB for better readability, a bit more documentation on variable usage

Added the pre-alarm feature that will allow users to set a configurable warning before the end of the injection. Added lots of comments for code documentation.
