Add more documentation to vugen.h
Expand README.md a bit.
Create y_core.c

This is achieved by moving various 'core' ylib functions from y_string.c to that (new) file.
Move various functions between y_core.c, y_string.c, and y_loadrunner_utils.c

This should make the function list a bit clearer. Though we still have a lot of work to do ..
Introduce Y_RAND_MAX

Let's not confuse people relying on the old RAND_MAX constant by upping that.
This may break old scripts using RAND_MAX in conjunction with y_rand, but there should not be too many of those.
Make y_browseremulation.c use Y_RAND_MAX
Compile fix.
Document y_is_vugen_run()
Stop documenting all the function removal warnings
More doxygen documentation changes.
Update the y_core.c description.
Give y_loadrunner_utils.c a description.
Further doxygen documentation updates, adding a bunch of 'see also' links.
Continuing the quest of documenting stuff.
.. welcome back, to Documentation Quest!
More doxygen documentation.
Document y_read_file_into_parameter()
Make y_read_file_into_parameter() return the number of bytes read.
Remove y_profile.c
Document y_user_data_point()
