Closes #20 - remove wait 1us during interrupt masking in loadSR. Not needed. Closes #19 - Added support for on/off commands Closes #18 - Set backlight initial state during initialization to off. Closes #17 - New SR3W class. Added documentation for new class Move some methods for the public interface of the LCD class to private, since they should never be called by the user.

First version of the generic 3wire latch library.
F Malpartida
Added backlight control on constructor. Added support for backlight control using POSITIVE and NEGATIVE logic.
F Malpartida
Merged changes to project head.
F Malpartida
Modified the send method to initialize correctly the LCD. Send method now has three modes: COMMAND, DATA, FOUR_BITS. setBacklight method check if a particular pin is mapped to a PMW.

closes #13 - rename private variable for LCD bit-mask pin. closes #15 - comments added to header files and method descriptions. closes #16 - added critical sections to fastIOs and associated usage on the LiquidCrystal_SR class. ref #14 - partially closed pending review.

Added doble quites back to the project.

Pulled in fast mode back into the project but added delays to createChar method to cater for slow LCDs.
F Malpartida
Begin method has been implemented in the top parent LCD class. The different ports now only have to provide methods to initialize the device driving the LCD, provide methods for the specifics to write to the LCD device. The begin method can be overloaded if necessary to initialize any HW that is implemented by a library and can't be done during construction.

Merged fastIO to main branch for release 1.2.0
F Malpartida
Corrected minor bugs and fixed timings for enable toggle so that it is more in-line with slow LCDs.

Removed un-necessary constructor methods: removed all those that contain lines and dots variables, since they are not used during initialization. These are initialized in the begin method. Added some comments by Ragnar - original author of the library - to clarify ASIC connectivity.

Corrected some indentation problems. Removed redundant _cols, _rows from child classes and moved them to parent virtual class. closes #7 - Support for 16x4 LCDs and their peculiar addressing.
F Malpartida
closes #5 - added 2000us delay to the LCD home and clear commands. It has been moved to the LCD.h header file as a constant to be more manageable. closes #6 - corrected range check for row addressing. Moved 37 us delay to the send method of the LiquidCrystal class since the delay is once the command is applied not on every nibble write in 4 bit mode.
F Malpartida
Adjusted timing on clear and home calls to be more generic, it seams that some LCDs need a longer time to execute the command. resolves #5
F Malpartida
Added conditional compilation of time to toggle LCD IOs depending on how optimized the digitalWrite operation is. The current version uses FAST_MODE by default, assuming that it uses the Arduino's SDK digitalWrite.
F Malpartida
Added generic I2C board control to define pin mapping to IO extender so that it is a generic library for the PCF8574.
F Malpartida
Added performance enhancements to the liquidCrystal library and the liquidCrystal_I2C library.
