Summarizes an AliyotMap by collapsing all adjacent aliyot. Finds any non-overlapping parts (e.g. special 7th aliyah or maftir)

makeSummaryFromParts(parts) ⇒ string

Returns a string representation of the leyning parts. Separate verse ranges read from the same book are separated by commas, e.g. Isaiah 6:1-7:6, 9:5-6. Verse ranges from different books are separated by semicolons, e.g. Genesis 21:1-34; Numbers 29:1-6.

This function does not modify aliyot. Instead, it returns a deep copy with aliyot['M'] replaced and sets reason.M (and in some cases the 6th and 7th aliyah, setting reason['7']).

If a special Haftarah applies, the result will have a haft property pointing to Haftarah object and sets reason.haftara.
