This is the third part of my new library collection (the already published parts are the "Bargraph",
"PS2 Keyboard Simulator" and the "Common output functions").

Same way usable (uniformized) LCD libraries. Every precompiled lib allows you to manage
up to four HD44780 compliant LCD. For all 8-bit PIC.

"..Lcd" prefix is used to distinct the type of the interface:
           where ".." may be: (none) B w3 w2 w1 N8 B8 (eg p16e_w2Lcd-4.mcl)

1.      Lcd ...... the usual nybble (4-bit) interface (most used)
2.   BLcd .....  the same but with Busy flag checking (faster)

       using HC595 as a port expander (3 separated libraries):

3. w3Lcd ..... 3-wire interface
4. w2Lcd ..... 2-wire
5. w1Lcd ..... 1-wire

6. N8Lcd ..... the normal full (8-bit) interface (smallest code)
7. B8Lcd ..... the same but with Busy flag checking

So there are seven different library (sum 7 * 3 = 21 "p*_....-4.mcl" file, in
accordance of the three different PIC family; p* = p16, p16e or p18).

Every library contains 6 'fundamental' functions for the four (0...3) LCD:
    Init - WriteChar - Command - UserChar - GotoYX - GotoYX_16x4
using a specific, library-dependent prefix (eg w1LcdX_Init, where X = 0..3)

In addition, they contain the 12 'common output' functions for the ..Lcd0:
   CstrOut - CstrNout - RstrOut - RstrNout - Hex2out - Hex4out
   BcdOut - Dec2out - Dec2out_J - Dec3out_J - Dec4out_J - Dec5out_J

Detailed description in the "LCD-libs_DOC.H".
A demo project is included to show the 1-, 2- and 3-wire interface circuits.
