FEATURE: Accept a slightly more general form of svarasthana notation
where the svarasthanas don't need to be separated by space. Each such "word"
of svarasthanas will be typeset within the same space allocated to
a stand-alone svarasthana that occurs on the line. If the number of
aksharas on the line is the same as what "aksharas per line" specifies,
then this means that each svarasthana in such a "word" will be typeset
using 1/N of the space allocated to an akshara where N is the length
of the word in number of svara or pause characters.
Reusing props.
Added notation files and updated Makefile to reflect them.
