Sorting Order: No Punctuation First

I. Description:
A base form contains no punctuation should be on the top of the sorting order.

II. Example
Alzheimers is chosen over Alzheimer's and Alzheimers' as the citation form because it does not contain punctuation.

{base=Alzheimer's
spelling_variant=Alzheimers
spelling_variant=Alzheimers'
entry=E0000236
    cat=noun
    variants=uncount
}

{base=Alzheimers
spelling_variant=Alzheimer's
spelling_variant=Alzheimers'
entry=E0000236
    cat=noun
    variants=uncount
}

{base=Alzheimer's disease
spelling_variant=Alzheimers disease
spelling_variant=Alzheimers' disease
entry=E0000237
	cat=noun
	variants=uncount
}

{base=Alzheimers disease
spelling_variant=Alzheimer's disease
spelling_variant=Alzheimers' disease
entry=E0000237
	cat=noun
	variants=uncount
}

III. Impacts (on Norm)
Results of NLP programs use citation forms might change accordingly. For examples, using above two LexRecords, the result of Norm (which uses -f:Ct) is changed accordingly between 2013- and 2014+:

• Input: Alzheimers' disease
• Results (2013-): alzheimer disease s
• Results (2014+): alzheimers disease

Similarly, the results of Norm (which uses -f:Ct) for the example below will be changed accordingly between 2013- and 2014+:

• Input: carcinoembryonic
• Results (2013-): carcino embryonic
• Results (2014+): carcinoembryonic

{base=carcino-embryonic
spelling_variant=carcinoembryonic
entry=E0015222
    cat=adj
    variants=inv
    position=attrib(3)
    position=pred
    stative
}

{base=carcinoembryonic
spelling_variant=carcino-embryonic
entry=E0015222
    cat=adj
    variants=inv
    position=attrib(3)
    position=pred
    stative
}

Please note that carcino-embryonic will be normalized to carcino embryonic in both versions because the replace punctuation with space flow component (-f:o) is processed before -f:Ct in Norm.

• Input: carcino-embryonic
• Results (2013-): carcino embryonic
• Results (2014+): carcino embryonic
