This function is used by select_one() to determine if one of a list of alias parameters is in the argument list
provided by the template.
Input:
args – pointer to the arguments table from calling template
alias – one of the list of possible aliases in the aliases lists from Module:Citation/CS1/Configuration
index – for enumerated parameters, identifies which one
enumerated – true/false flag used to choose how enumerated aliases are examined
value – value associated with an alias that has previously been selected; nil if not yet selected
selected – the alias that has previously been selected; nil if not yet selected
error_list – list of aliases that are duplicates of the alias already selected
Returns:
value – value associated with alias we selected or that was previously selected or nil if an alias not yet selected
selected – the alias we selected or the alias that was previously selected or nil if an alias not yet selected

Chooses one matching parameter from a list of parameters to consider. The list of parameters to consider is just
names. For parameters that may be enumerated, the position of the numerator in the parameter name is identified
by the '#' so |author-last1= and |author1-last= are represented as 'author-last#' and 'author#-last'.

Gets the display text from a wikilink like [[A|B]] or [[B]] gives B
The str:gsub() returns either A|B froma [[A|B]] or B from [[B]] or B from B (no wikilink markup).
In l(), l:gsub() removes the link and pipe (if they exist); the second :gsub() trims whitespace from the label
if str was wrapped in wikilink markup. Presumably, this is because without wikimarkup in str, there is no match
in the initial gsub, the replacement function l() doesn't get called.

Strip wiki italic and bold markup from argument so that it doesn't contaminate COinS metadata.

markup a title have, as a result, provided valid markup. When they don't, some single apostrophes are left behind.
