abjad

This is a little library meant to facilitate calculating the numerical abjad value of a string of Arabic or Persian text.

lib.rs:

This library is meant to facilitate calculating the numerical abjad value of a string of text in Arabic or Persian (support for other Arabic-script languages may be added over time).

At the moment, this simply adds three methods for &str:

• abjad returns a best-effort value, ignoring unrecognized characters.
• abjad_collect_errors also records unrecognized characters in a Vec.
• abjad_strict returns an error as soon as any character is not recognized.
