String Functions

##String Functions

All of the AQL string functions are mapped to System.String.

###Example

    dv.FacebookUsers.Select(u => u.name[0]);

will generate

    for $u in dataset FacebookUsers return string-to-codepoint($u.name)[0]

For an example of each function, view the relevant tests.
