function _footnotes_helper_find_footnote in Footnotes 7.3

Same name and namespace in other branches

1. 6.2 footnotes.module \_footnotes_helper_find_footnote()
2. 7.2 footnotes.module \_footnotes_helper_find_footnote()

Search the $store_matches array for footnote text that matches and return the value.

Note: This does a linear search on the $store_matches array. For a large list of footnotes it would be more efficient to maintain a separate array with the footnote content as key, in order to do a hash lookup at this stage. Since you typically only have a handful of footnotes, this simple search is assumed to be more efficient. (but was not tested).
