[emacs-bidi] Hebrew input methods

[Yair F]

Hello all,

I intend to do some work related to composition of vowel and
cantillation marks..
To test the composition code a way to add these marks is needed. As
the OS does not support adding these an input method is in place.

There are 4 input methods I intend to add to Emacs

1. SI 1452:  Somewhat complex and only partially implemented on common
OS. It doesn't include cantillation marks.

2. LyX: Used in X environment - more logical and easy to use,. Also
doesn't include cantillation marks.

3. Biblical-Tiro: A complete method. However, it is directed towards
biblical Hebrew and is not convenient for modern Hebrew users.
The tiro Guide is here:

4. Emacs: For a lack of a better name. Intend to be modern Hebrew
oriented and complete.

The grey background image is a common implementation of a Hebrew
keyboard. the black letters are the actual keys assigned.
For Vowel marks I added them illustrated with base letters, the input
method only add the mark.

I would greatly appreciate any comments or suggestions you have for
those mappings.

Thanks,
Yair
