Update for Julia 1.7

Update for compatibility with Julia 1.7.

If you're using Julia ≤ 1.6, please stay with version 0.21.

Meeting with Julia's meta-programming

By separating Julia QuoteNode with Symbol with predicates :/1 and $/1 respectively, Jurassic.pl can manipulate Julia's AST expressions (Expr type). It has the following basic functions:

• Construct Julia expressions with jl_expr/2;
• Evaluate Julia expressions with Julia's eval/1;
• Unify Prolog terms and Julia expressions.

Enjoy writing Julia code with Prolog :)

v0.13

• Updated the syntax parsing method, fixed many bugs of parsing Prolog expressions into Julia;
• Support Julia anonymous functions with operator ->>;
• Multi-dimension array assignment, but still cannot unify them with Prolog lists;
• Can use tuple/1 to handle multiple returns from Julia functions.

v0.12

Fixed some bugs in function calls.

v0.11

• Support Julia Package.function calls. If the Package is started with uppercase, please quote it when calling, such as 'Package'.function.
• Support operators like .+, .*, .^ and +=, *=, etc.
