This method expects a file located relative to the current working
directory, which contains a Lexer class. By default, it expects the
Lexer to be name CustomLexer; you can specify your own class name
as the second argument to this function.
Users should be very careful with the input, because this method
is equivalent to running eval on the input file.
Raises ClassNotFound if there are any problems importing the Lexer.

Lookup all lexers that handle those filenames primary (``filenames``)
or secondary (``alias_filenames``). Then run a text analysis for those
lexers and choose the best result.
